Answer:
81 in^2
Step-by-step explanation:
Well the formula to find an area of a triangle is (bh) / 2
In this case the base is 18 and the height is 9
18*9=162
162/2=81
Divide them and then multiply
False
<span>(9/ 4)/ 18
= 9/4 * 1/18
= 9/72
= 1/8 </span>
I believe the volume of the shape is 210mm. the formula is v=lwh. so you multiply all the numbers to get 210. hope that helped!
