Answer:

84

Step-by-step explanation:

first calculate the rectangle (6* 10  = 60) and then add that to the area of the triangles. 1/2(4) * 6= 2 * 6 = 12, and since there are two triangles: 12* 2 = 24, add that to the area of the rectangle and you get 84.

mart [117]

Answer:

$76.50

105.40 + 47.60 = 153.00

70% - 20% = 50%

$153.00 divided by 50%  = $76.50
