A large rectangle is made by joining three identical small rectangles as sh
x cm
The perimeter of one small rectangle is 21 cm.
The width of one small rectangle is x cm.
Work out the perimeter of the large rectangle.
The final line of your answer should be of the form,
Perimeter of large rectangle is ... cm

The perimeter of the larger rectangle is: 35 cm

The formula for determining the perimeter of a rectangle = 2(length + width)

Given:

Equation that expresses the perimeter of one small rectangle will be:

2(2x + x) = 21

4x + 2x = 21

6x = 21

x = 21/6

x = 3.5

Perimeter of the larger rectangle = 2(2x + 3x) = 2(5x)

Perimeter = 2(5(3.5))

Perimeter = 35 cm

Therefore, the perimeter of the larger rectangle is: 35 cm.

The Perimeter of large rectangle is 35 cm

Step-by-step explanation:

For the small rectangle we are given the following :

The perimeter of one small rectangle is 21 cm.

The width of one small rectangle is x cm.

The formula for the perimeter of a rectangle = 2(Length + Width)

2(Length + Width) = 21

A rectangle has 2 lengths and 2 width

In the diagram the width is longer than the length hence

Let the length = x

Let the width =2 × x = 2x

2(2x + x) = 21

2(3x) = 21

6x = 21

x = 21/6

We are told that each of the rectangles are similar , hence we have

The perimeter of the large rectangle =

10x

From the calculation above:

x = 21/6

Therefore, the perimeter of the rectangle = 10 ×21/6

The Perimeter of large rectangle is 35 cm
