Identify the sides and find perimeter of a quadrilateral
The perimeter is the sum of all sides of a closed figure.
Finding the sides and perimeter of the following figures.
Sides = AB, BC, CD, DA
Perimeter = AB + BC + CD + DA
= 3 + 6 + 8 + 2 = 19
In a given square all the sides are equal.
Therefore, Perimeter of a square = PQ + QS + SR + RP
= 8 + 8 + 8 + 8 = 32
Perimeter of a square = 32cm
In a given rectangle opposite sides are equal.
Perimeter = LM + MN + NO + OP
= 9 + 3 + 9 + 3 = 24
Perimeter = 24cm
Perimeter = XY + YZ + ZX
= 7 + 7 + 7 = 21
Perimeter = 21cm
