Two rectangles have the same area. The first has sides 20 cm and 12 cm. The second has one side 15 cm. What is the other side of the second rectangle?
Show answer & explanation
Correct answer: C
Explanation
Area of the first rectangle = 20 × 12 = 240 cm²
The area of the second rectangle is also 240 cm².
One side of the second rectangle is 15 cm.
Therefore, the other side = 240 ÷ 15 = 16 cm.
