Answer 2

Answer:

71.5 units

Step-by-step explanation:

side 1 + side 2+ side 3= perimeter

8 + 11+ side 3 = 32 (given)

19 + side 3 = 32

side 3 = 32 - 19

side 3 = 13

area: 1/2 (base x height)

[ always take the largest side as the base and the second largest side as the height]

1/2 x 13 x 11

71.5
