Answer:

1. 117 sq. in.

2. 168 sq. in.

3. 99 sq. in.

Explanation:

1. base x height = area

13 x 9 = 117 sq. in.

2. 1/2 x height x (base + base)

1/2 x 14 x (15 + 9)

1/2 x 14 x 24

Multiply 1/2 by 14 to get 7

7 x 24 = 168 sq in.

3. 1/2 d x d

1/2 x 18 x 11

Multiply 1/2 by 18 to get 9

9 x 11

Multiply 9 x 11 to get 99

9 x 11 = 99 sq. in.
