The perimeter of a square is 32 cm, and the perimeter of a pentagon with equal sides is 50 cm. Which polygon has a shorter side and by how many cm?
The square has 4 sides and they are equal to each other. We calculate the length of the side of the square:
a = 32/4 = 8 cm.
Let’s calculate the length of the side of the pentagon:
b = 50/5 = 10 cm.
Let’s compare the sides of the figures:
a <b
b – a = 2 cm.
Answer: the side of the square is 2 cm shorter than the side of the pentagon.
