Question

The length of a rectangle is $16m$ less than two times its breath . if the perimeter of the rectangle is $112m$,find the length and the breath

Answer 1

Let l be the length of rectangle

and b be the breath of rectangle

A/Q,

$l=2b-16⟶\left(1\right)also,perimeter=112m\Rightarrow 2(l+b)=112\Rightarrow 2(2b-16+b)=112\left(from\right(1\left)\right)\Rightarrow b=24mand,l=2.24-16\Rightarrow l=32m$
