Question

The length of a rectangle is 2m more than its breadth... Find the dimensions of the rectangle if its perimeter is 56m.....

Answer 1

let the breadth be x.
then length is 2 +x
perimeter of rectangle =2 (l+b)
56=2 (2+x+x)
56=2×(2+2x)
56=4+4x
56-4=4x
52=4x
x=52/4
=13

so breadth (x)=13m
and length is 2 +13
15m

hope you liked this answer. pls mark the answer as brainliest.

Answer 2

Let the breadth be x
Length = x + 2
Perimeter of rectangle=2(l+b)
56 = 2(x+x+2)
56=2(2x+2)
56=4x+4
56-4=4x
52=4x
X=13
Length= 13
Breadth= 13+2=15
