Find the area of a rectangle if it is 15 cm wide and 1.2 times longer.

In order to find the area of a rectangle if its width is 15 cm and its length is 1.2 times more, let’s first of all find the length of the rectangle.

Let’s calculate the length of the rectangle. To do this, multiply the width by 1.2.

15 cm * 1.2 = 18 cm rectangle length.

Let’s remember the formula for finding the area of a rectangle.

S = a * b;

The area of the rectangle is equal to the product of the length and the width. We just have to substitute the values and calculate:

S = 15 * 18 = 270 cm2 area of a rectangle.

Answer: 270 cm2 area of a rectangle.
