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

b)60

c)30

d)40
​

Answer 1

Answer : correct option is d) 40 m

Step-by-step explanation:

let the breadth of a rectangle be x meters

then length of a rectangle is 2x meters

perimeter if a rectangle is 240m

by using formula perimeter of rectangle ,

perimeter of rectangle = 2(lenght+ breadth)

240 = 2 ( 2x + x)

240/2 = 3x

120/3 = x

40 = x

therefore the breadth of rectangle is 40 m
