Question

A rectangle has an area of 15 square yards. The width is 2 yards less than the length. What is the length, in yards, of the rectangle?

A: 2 yards
B: 3 yards
C: 5 yards
D: 15 yards​

Answer 1

Answer: 5

Explanation:

length = x

Width=x-2
Area=lw

15=(x)(x-2)

15=x^2-2x

0=x^2-2x-15

Quadratic formula:

X=-15

X=5

the length is 5 because the length can’t be negative
