Question

If the perimeter of the given figure is 44 cm, what is the measure of the unknown side in the given figure?

Answer 1

Sum of the length and breadth = Half of the perimeter of the figure
Sum of the length and breadth = 44 ÷ 2
= 22 cm
Length = 22 - 10
= 12 cm
$\therefore$ 12 = 3 + Unknown side
$\therefore$ Unknown side = 12 - 3
= 9 cm
