Question

The length of a rectangle is two times its breadth. The perimeter of a rectangle is 240 m. The breadth of the rectangle is
A-50 m
B-60 m
C-30 m
D-40 m

Answer 1

Answer:

Step-by-step explanation: 50+60+30+40

180

Answer 2

Answer:

D - 40 m

Step-by-step explanation:

Let the breadth of the rectangle be x. So the length of the rectangle is 2x.

Perimeter of a rectangle = 2(l + w)

240 m = 2(x + 2x)

240 m = 2x + 4x

240 m = 6x

6x = 240 m

x = 40 m

Therefore, the breadth of the rectangle is D - 40 m
