What is the area of the trapezoid?

144 in²

Step-by-step explanation:

You can find the area of the rectangle then add the area of the two triangles, but that's just a square. (The equation can also be used, but since the lines are there, this is the method I'll use).

Area of rectangle: 8 * 10 = 80 in²

Area of the two triangles: 2 * 1/2 * 8 * 8 = 64 in²

Total: 80 + 64 = 144 in²

11

step-by-step explanation:

32.50-7.50=25

225/25=11

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
