The length of the rectangle is 6cm and its width is 2cm less. What is the length of the side of a square with a perimeter equal to the perimeter of the rectangle?
In order to find out the width of the rectangle, subtract 2 cm from the length.
b = 6 cm – 2 cm = 4 cm.
Next, let’s calculate the perimeter of the rectangle. Multiply the sum of the length and width by 2.
P = (6 cm + 4 cm) * 2 = 20 cm.
The perimeter of the square is equal to the perimeter of the rectangle and is equal to 20 cm.
Find the side of the square. Divide the perimeter of the square by 4.
a = 20 cm ÷ 4 = 5 cm.
Answer: the side of the square is 5 cm.
