Question

A rectangle is drawn so that the width is 1 feet shorter than the length. The area of the rectangle is 56
square feet. Find the length of the rectangle.

Answer 1

Answer:

7 feet

Step-by-step explanation:

length=x

width= x+1

x(x+1)=56

X2+x=56

X2+x-56=0

(x+8)(x-7)

x equals -8 or 7. Since length can't be a negative number, it's 7.
