Question

The length of a rectangle is 4 metre less than 3 times its breadth. If the perimeter of the
rectangle is 112 metre , find the length and breadth

Answer 1

Let l be the length of rectangle

Let l be the length of rectangleand b be the breath of rectangle

Let l be the length of rectangleand b be the breath of rectangleA/Q,

Let l be the length of rectangleand b be the breath of rectangleA/Q,l=2b−16⟶(1)also,perimeter=112m⇒2(l+b)=112⇒2(2b−16+b)=112(from(1))⇒b=24mand,l=2.24−16⇒l=32m
