Question

A rectangular field has a perimeter of 100 m the length of the field is 10 m more than the breath.find the area of the field

Answer 1

Perimeter= 100
Breadth be x.
So length = 10+x
.
. . = 2 (x+10+x)= 100
=2x+20+2x =100
= 4x +20 =100
=4x = 100-20
= 4x = 80
= x = (80/4)= 20

Therefore, breadth is 20m and
Length is (20+10)=30m

So area = l×b
= 20×30
= 600m
