Question

Write the name of the shape. Then find the perimeter.ABCD is a _______________. Its perimeter is _________ units.PQRS is a _______________. Its perimeter is _________ units.

Answer 1

Given two shapes

We will find the name of the shape and its perimeter.

Shape ABCD:

Length = AD = 8 units

Width = AB = 4

AB⊥AD, So, the name of the shape is Rectangle

perimeter = 2*(AB+AD) = 2*(4+8) = 2 * 12 = 24 units

Shape PQRS:

Length = PQ = 4 units

Width = PS = 4 units

As PQ = PS, and PQ⊥PS

So, the name of the shape is Square

perimeter = 4 * 4 = 16 units
