C+3ci=4+di find the values of c and d that make each other true

105 sq. cm

Step-by-step explanation:

To caculate area of this compond shape, we have to divide it in 2 parts. There is a triangle and a rectangle.

First, lets find area of the rectangle

A = l x w

A = 15 x 6 = 90 sq. cm

Now, for area of triangle

A = 1/2 x base x height

base = (15-9) = 6 cm

height = (11-6) = 5 cm

A = 1/2 x 6 x 5

A = 15 sq. cm.

Area if the compound shape = 90 + 15 = 105 sq. cm.
