Question

The l of rectangle is 16 m lessthan two times its breadth if the perimeter ofthe rectangle is 112 m find the length and breadth

Answer 1

Let breadth = x
Let length = 2x-16
A/Q 2(l+b) = 112
2(x+2x-16)=112
2(3x-16)=112
6x-32=112
6x=144
x=24

∴Breadth = x = 24cm
Length = 2x-16 = 2x24-16 = 32cm
