Question

A rectangle has perimeter of 50 metres. If its length is 13 metres more than its breadth, then its area is:

Answer 1

hello

let breadth = X

and length = X+13.

perimeter = 2(l+b)

50 = 2(X+13+X)

50= 2(2x+13)

50= 4x+26

4x= 50-26

X = 24/4

X= 6.

hence breadth = 6 metres

and length X+13 = 6+13 = 19 metres.

area = length x breadth

19 x 6 = 114 meter^2.

hope it helps you
