The side of the square ABCD is 7 cm, and the sides of the rectangle EFKM are 8 cm and 6 cm.

The side of the square ABCD is 7 cm, and the sides of the rectangle EFKM are 8 cm and 6 cm. Construct these shapes and compare their perimeters and areas.

Remember that all sides of a square shape are the same. The perimeter of the figures is the sum of all four sides.
Let’s calculate the perimeter of the square and the perimeter of the rectangle by adding all their sides together.
P square = 7 cm + 7 cm + 7 cm + 7 cm = 14 cm + 14 cm = 28 cm.
P rectangle = 8 cm + 6 cm + 8 cm + 6 cm = 14 cm + 14 cm = 28 cm.
The perimeters of these two figures are the same.
Next, we calculate their areas by multiplying the length by the width:
S square = 7 cm * 7 cm = 49 cm2.
S rectangle = 8 cm * 6 cm = 48 cm2.
