Question

The width of a rectangle is 32 inches shorter than twice its length. The area of the rectangle is 72 square inches.
What is the length of the rectangle?

Answer 1

Answer:

18inches

Step-by-step explanation:

Let l be the length and breadth be ,b=2l-32

Area of rectangle=72

l×B=72

l(2l-32)=72

2l²-32l-72=0

Dividing by 2

we get, l²-16l-36=0

l²-18l+2l-36=0

l(l-18)+2(l-18)=0

(l+2)(l-18)=0

l=-2,18

Since length cannot be negative 18 is the length.
