Question

The length of a rectangle is two times its width. The perimeter of the rectangle is 180 cm. Find the dimensions of the rectangle and also find its area.

Answer 1

HEY MATE HERE IS YOUR ANSWER
__________________
Length of rectangle = 2x

Breadth of rectangle = x

Perimeter of rectangle = 180cm

➡️ 180 = 2 ( 2x +x)

➡️ 3x = 180/2

➡️ 3x = 90

➡️ x = 30cm

Breadth = 2(x) = 2(30) = 60cm

Therefore,

Length of rectangle = 60 cm
Breadth = 30cm

Area of rectangle = l × b

➡️ 60 × 30

➡️ 1800 cm

Answer 2

♐Hey dear.

♐Here is your answer.

♐Let the breadth be x.
♐Then the width would be 2x.

♐According to the question the perimeter of the rectangle is 180cm.

♐Then,

=>2x+4x=180.
=>6x=180.
=>x=180/6.
=>x=30.

♐That means the width is 30 cm and the length is 2 times th width that is 60cm.


♐Now the area will be ...

♐Lenght*Width

=>30*60
=>1800 (Ans).

♐Hope it helps
