Question

The length of a rectangle is 1 units more than the width. The area of the rectangle is 56 units. What is the length, in units, of the rectangle?

Answer 1

Answer:

8

Step-by-step explanation:

Width is x.

Length is (x + 1).

Area = length*width

56 = x(x+1)

x² + x - 56 = 0

(x+8)(x-7)=0

x = - 8, or x = 7

"- 8" is impossible for width.

So, width x = 7

Length = (x+1) = 7+1 = 8
