Given : irregular figures.
To Find : area of each irregular figures.
Solution:
Area rectangle = length * breadth
Area of square = side²
Fig1 : Assuming side 6 a square
Area = 12 * 8 + 6²
= 96 + 36
= 132 cm²
Fig2 : Assuming side 4 a square
Area = 9 * 6 + 4²
=54 +16
= 70 cm²
Fig 3 : 21 is divided in 3 equal part hence area
= 21 * 9 + (21/3)²
= 189 + 49
= 238 cm²
Fig 4 : 18 is divided in 3 equal part hence area
= 18 * (18/3) + 7 * (18/3)
= 25 * 6
= 150 cm²
Fig 5
Area = 32 * (36 - 10) + 10²
= 932 cm²
or 36 * 32 - ((32 - 10) * 10
= 932 cm²
