A rectangle has an area of 900square inches. The length of the rectangle is 2.25 times the width.Find the dimensions
Alexeev081 [22]

Answer:

Length = 45 inches and Width = 20 inches

Step-by-step explanation:

Let the width be w.

Length(l)=2.25w

Area = 900 in^2

The formula for the area of a rectangle is Area = length * width

So substituting our values we get:

A=2.25w*w\\900=2.25w*w\\2.25w^2=900\\w^2=\frac{900}{2.25} \\w^2=400\\w=\sqrt{400} \\w=20

So we get width = 20 inches

Length = 2.25w

so Length= 2.25*20

=45 inches
