# Perimeter of Rectangle | How to Find the Perimeter of a Rectangle

We’ll focus on learn how to discover it right here. round a rectangle. we all know the circumference of a rectangle whole size of the border (distance) rectangle.

We all know that in a rectangle, two reverse sides are equal. So, PQ = SR and PS = QR

If PS = l and PQ = b

Perimeter of rectangle = PQ + QR + RS + SP

= b + l + b + l

= 2b +2l

Once more,

ABCD is a rectangle. We all know that reverse sides of a rectangle are equal.

AB = CD = 5 cm and BC = AD = 3 cm

Thus, the perimeter of rectangle ABCD = AB + BC + CD + AD = 5 cm + 3 cm + 5 cm + 3 cm = 16 cm

It may be written as 5 cm + 5 cm + 3 cm + 3 cm.

= (2×5) cm + (2×3) cm

= 2 (5 + 3)cm

= 2×8cm

= 16cm

To search out the perimeter of a rectangle, we add the size and width twice.

Perimeter of rectangle = 2 (size + width)

A rectangle is a four-sided form;

Reverse facet lengths are equal.

The lengthy facet is named the size and the quick facet is named the width.

All angles are equal to 90° (proper angle).

Within the determine above, ABCD is a rectangle.

Three kids discovered the perimeter of this rectangle utilizing three completely different strategies.

onest technique:

Perimeter = 6 cm + 4 cm + 6 cm + 4 cm = 20 cm

2nd technique:

Perimeter = (2 6 cm) + (2 4 cm) = 12 cm + 8 cm = 20 cm

3rd technique:

Perimeter = 2 (6 cm + 4 cm) = 2 cm × 10 cm = 20 cm

All three strategies gave them the identical response.

Perimeter of rectangle = size + width + size + width

= (2 size) + (2 width)

= 2 (size + width)

Phrase Issues Concerning the Perimeter of a Rectangle:

Let’s think about some examples of the perimeter of a rectangle:

one. The size of the rectangle is 4 cm, and the width is 2 cm. Discover its environment.

Resolution:

Size = 4cm

Width = 2cm

Subsequently, the perimeter of the rectangle is

= 2 (size + width)

= 2 (4 + 2)cm

= 2×6cm

= 12cm

2. Discover the perimeter of rectangle ABCD with sides 6 cm and 5 cm.

Resolution:

Perimeter of rectangle ABCD

= 6cm + 5cm + 6cm + 5cm

= 22cm

3. Discover the perimeter of a rectangle 12 cm lengthy and eight cm vast.

Resolution:

Size = 12cm

Width = 8cm

Perimeter = 2 (size + width)

= 2 (12cm + 8cm)

= 2 × 20 centimeters

= 40cm

4. An oblong swimming pool is 9 m lengthy and 4 m vast. Discover the world of ​​the pool.

Resolution:

Size of rectangular swimming pool = 9 m

Width of rectangular swimming pool = 4 m

Subsequently, the circumference of the oblong swimming pool

= 2 (size + width)

= 2 (9 + 4) m

= 2 (13) m

= 2 × 13m

= 26 M

5. A rectangle is 4.5 m lengthy and 1.5 m vast. Discover the setting.

Resolution:

Size = 4.5m

Width = 1.5m

Perimeter = 2 (size + width)

= 2 × (4.5m + 1.5m)

= 2×6m

= 12m

Subsequently, the perimeter is 12 m.

6. An oblong graphics card measures 8 m by 6 m. Robert needs so as to add a stripe border across the video card. What’s the size of the strip it’ll want? If the ribbon prices \$15 per meter, how a lot cash does Robert want to purchase the ribbon?

Resolution:

Size of video card = 8 m

Width of video card = 6 m

Perimeter of video card = 2(Size + Width)

= 2(8 + 6)m

= 2×14m

= 28 m.

The meter of the ribbon is 15 TL.

Subsequently, the whole value for the 28m lengthy strip = \$15 × 28

= \$420.

Questions and Solutions Concerning the Perimeter of the Rectangle:

1. Discover the perimeter of the rectangles whose dimensions are as follows.

(i) size = 11 cm width = 9 cm

(ii) size = 5 cm width = 2 cm

(iii) size = 10 cm width = 8 cm

(iv) size = 15 cm width = 2 cm

one. (i) 40 cm

(ii) 14cm

(iii) 36cm

(iv) 34cm

Circumference of Rectangular Phrase Issues

2. The perimeter of the rectangle is 40 cm. If its size is 8 cm, how lengthy is its breath?

2. 12cm

3. Sam runs round an oblong park 450m lengthy and 300m vast. Discover the whole distance traveled if he makes 10 laps within the park.

3. 15000 m

4. A gardener needs to fence his rectangular backyard with wire. The size of the backyard is 25 m and its width is 16 m. Discover the size of the wire he wants to purchase.

4. 82 meters
