PLZ HURRY IT'S URGENT!!!

The area of a rectangle is 56.25 square inches. The length of the rectangle is 12.5 inches. What is the width of the rectangle? A. 4.5 inches B. 5 inches C. 43.75 inches D. 68.75 inches

Answer 1

A. 4.5 inches

Explanation:

The area of a rectangle is equal to length times width. Therefore divide 56.25 (area) by 12.5 to get width because division is the inverse operation of multiplication: 56.25 sq. in. / 12.5 in = 4.5 in

Answer 2

The width of the rectangle is: A. 4.5 inches

Explanation:

The formula for the area of a rectangle is:

`A =  w * L`

Where: w= width, L=length

We know :

`A=56.25inch^(2)`

L = 12.5 inches

so the formula for the width would be:

`w = (A)/(L)`

w= 4.5 inches
