B. 20

Step-by-step explanation:

Hi to answer this question we have to apply the next formula:

Area of a triangle: base x height (altitude) x 1/2

Replacing with the values given:

A =4 2/3 x 8 4/7 x 1/2

A= (4x3+2)/3 x (8x7+4)/7 x 1/2

A = 14/3 x 60/7 x 1/2 = 840/42=20 square feet

So, the correct option is B.20
