Question:
Image below

20 cm
Area = Length × Width
Area = 24 cm²
Area = Length × Width
Length = 24 = Length × 3
Length = Length = 24 ÷ 3
Length = Length = 7 cm
Perimeter = 2 × (Length + Width)
Perimeter = 2 × (7 cm + 3 cm)
Perimeter = 2 × 10 cm
Perimeter = 20 cm
If the width of the rectangle is 3 cm and the area of the rectangle is 3 square cm. So the perimeter of the rectangle is 20 cm.
