➷ 8) (10 x 15) / 2 = 75
(this is the area of the whole shape, including the non shaded part)
Now work out the area of the non shaded part:
(6 x 9) / 2 = 27
Subtract this area from the total area:
75 - 27 = 48
The area of the shaded part is 48 square yards
9) Find the area of the whole shape (including the non shaded parts)
13 x 7 = 91
Work out the areas of both non shaded regions:
4 x 3 = 12
2 x 1 = 2
Add these two values together:
12 + 2 = 14
Subtract this value from the total area:
91 - 14 = 77
The area of the shaded part is 77 cm^2
