172.9
You find it by multiplying each side of the triangle by the height (9) and adding the results together.
A(lateral) = 8 * 9.1 + 3 * 9.1 + 8 * 9.1
= 72.8 + 27.3 + 72.8
= 172.9
The answer is 9y^2x(the 2 goes on top were the arrow is ) Hope this was helpful!

Step-by-step explanation:
D
area of rectangle=25*12=300
6 % of area=300*6 %=18
area of D=1/2 *6*6=18
so D
Using the cosine rule we can work out the length of the side opposite the indicated right angle which came to be 15mm
then the final answer came to be 163mm^2
