In the given figure, there are two right angled triangles.
Area of triangle = 1/2 × b × h
Area of shaded region = area of larger triangle - area of smaller triangle
= 1/2 × 15 × 18 - 1/2 × 8 × 9
= 135 - 36
= 99 ft^2
Thus, area of shaded region is 99 ft^2.

1,3 u = -3,25
1,3u ÷1,3 = -3,25 ÷ 1,3
u = -2,5
38 10 49 11 60 12..

27 - 16 = 11
8 - 7 = 1
So for each small number add 1 ad for the big add 11
