The width of a rectangle is 5 meters less than its length. If the area is 84 square meters, what is the WIDTH of the rectangle?

7 m

Step-by-step explanation:

If the width of rectangle is a

the length of a rectangle is a+5

the rectangle area formular is the width × the length

a(a+5) = 84

a^2 + 5a = 84

a^2 + 5a - 84 = 0

(a-7)(a+12) = 0

a = 7, -12 but we cut the -12 out due to the width must show the positive values.

a shows the only one answer 7

the width = 7 m

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general
