Question:

What is the perimeter of the shape seen in the figure?

A 70 cm
Explaination

The angles in the figure tell you that the triangle must be equilateral (All of corners of the triangle is 60 degree (150 - 90 = 60)). That means all three sides of the triangle are 10 cm. This also means the base of the figure is 10 cm + 6 cm = 16 cm. the left side is 14 cm, adding up the values given on the right side. Thus, the total perimeter is 10 cm + 10 cm + 14 cm + 16 cm + 6 cm + 6 cm + 8 cm, which is 70 cm total.
