Question

the length of a rectangle is 7 M more than its breath. if its perimeter is 50m. Find the length and breadth of the rectangle.

Answer 1

let breath = x
length = x+7
according to question
perimeter of rectangle = 2 × (length +breath )
50 = 2 × ( x+7 +x )
50 =2 × ( 2 x + 7 )
50 = 4 x + 14
4 x =. 14 - 50
4x = 36
x =36/4
x=9

breath= 9metre
length = 9+7 = 16 metre
