**Question**

A 4 inch wide by 6 inch long photo is enlarged 25%. What is the area?

**Answer** **STEP 1: **From the given information, we understand that the photo is in the shape of a rectangle having dimensions 4 inch by 6 inch.

It is given that the photo is enlarged by 25%. This means that the dimensions increase by 25%.

**STEP 2: **Now the measures of the length and width of the enlarged photo are known, we can find its area. Make use of the

formula of a rectangle,

*A = lw*.

In the formula,

*l* stands for the length and

*w* stands for the width.

Substitute for the two variables.

The area of the photo after enlargement is

**37.5 square inches**.
