The area of a rectangle is 54 square cm. The length of the rectangle is 9 cm. What is the perimeter (in cm) of the rectangle?
Show answer & explanation
Correct answer: C
Explanation
Given:
Area of the rectangle = 54 cm²
Length = 9 cm
According to the formula:
Area = Length × Width
Perimeter = 2(Length + Width)
Width = 54 ÷ 9 = 6 cm
Perimeter = 2(9 + 6) = 30 cm
