| **The area of one rectangle is equal to the area of the other rectangle. the length of the first rectangle is 18 cm, and the width is 15 cm. What is the width of the second rectangle if its length is 27 cm?**

Let’s first calculate the area of the first rectangle. Let’s multiply its width by its length.

S1 = 15 cm * 18 cm = 270 cm².

The area of the second rectangle is equal to the area of the first and is equal to 270 cm². To find out the width of the second rectangle, divide its area by its length.

a = 270 cm² ÷ 27 cm = 10 cm.

Answer: The width of the second rectangle is 10 m.
