Answer 1

Answer:

A.

Step-by-step explanation:

Find the area of the triangle: 26-20=6. 14x6=84/2=42. Now that we calculated the triangle's area, we need to find out the rectangle's. 20x14=280. Add them up: 280+42=322 mm^2. Triangle: b x h/2. Rectangle: l x h.

Answer 2

Answer:

A. 322 mm^2

Step-by-step explanation:

The area of the rectangle is 14 times 20

14 x 20 = 280

The area of the rectangle is 1/2 times 14 times 6

1/2(14)(6)=42

Finally add 280 and 42 and the answer is 322
