Question

A rectangular field has a perimeter of 100 meters. If its length exceeds its width by 10 meters, find the dimensions of the rectangle.

Answer 1

Answer:

length = 30m

breadth = 20m

Step-by-step explanation:

let breadth be x metres

then, length will be (x + 10) m

perimeter = 2 ( l + b )

100 = [ ( x + 10 ) + x )

50 = 2x + 10

40 = 2x

x = 20

hence b = 20 m

l = 20 + 10 = 30 m
