Answer:
C
Step-by-step explanation:
To find the area of the base of the prism, you would first multiply 7 1/2 and 2 1/4, which would leave you with 16.875. Next, you would divide by 2, which gives you 8.4375. Rounding up, you would have the answer C.
90*.1=9
90-9=81
81
190*.200=38
190-38=152
152
Im not technically sure whate it would be but i would imprevise by saying you can save up u can also put more effort to work
A = 3W² + W + 1/8πW²
rectangular window is L x W
semicircle is 1/2 πr²
r = 1/2 W
L = 3W + 1
A = W(3W + 1) + 1/2 π(1/2W)²
