Step-by-step explanation:

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

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

[tex]A = (B * H )/2[/tex]

  • Plug in given values.

[tex]A = (9*7)/2[/tex]

  • Multiply within parentheses.

[tex]A = (63)/2[/tex]

  • Divide by 2.

[tex]A = 31.5[/tex]

Answer:

D. 31.5 sq. units
