Question

The length of a rectangle is 7 inches more than 2 times the width. If the area of the rectangle is 114 square inches, find the length and the width.
?????????????

Answer 1

let w = width

length is 7 inches more than twice the width so

l = 2w + 7

area is 114 so

(2w + 7)w = 114

=> 2w^2 + 7w = 114

=> 2w^2 + 7w - 114 = 0

solve for w
