Answer 1

Explanation:

For this, we'll use a formula for the area of a triangle.

Area (A) = ( Base (B) * Height (H) ) / 2

`A = (B * H )/2`

• Plug in given values.

`A = (9*7)/2`

• Multiply within parentheses.

`A = (63)/2`

• Divide by 2.

`A = 31.5`

Answer:

D. 31.5 sq. units

Answer 2

D. 31.5 sq. units

Explanation:

The area of a triangle is

A = 1/2 bh

A = 1/2 ( 9)(7)

A = 63/2

A = 31.5 units^2
