Answer:
8
Step-by-step explanation:
8 × $70 = $560
20 × $140= $2800
$560 + $2800 = $3360
Answer:
53
Step-by-step explanation:
1) Take the area of the rectangle from origin to Point B. We see that it is 8 * 11 = 88 units of area
2) We subtract all the triangles in the rectangle that are not covered by the shape.
So
- Triangle FAPoint(0,-8) area = 1/2 * 2 * 5 = 5
- Triangle FEPoint(0,-3) area = 1/2 * 3 * 4 = 6
- Rectangle P(0,0) P(0,-3) P(6,-3) P(6,0) area = 6 * 3 = 18
- Triangle DP(6,0)P(11,0) area = 1/2 * 5 * 3 = 7.5
Take the area of the big imaginary rectangle and subtract the area of all the smaller triangles and the smaller rectangle
88 - 5 - 6 - 7.5 - 18 = 51.5
Done!
