all you do is multiply to get the area
Y=19, It's a straight horizontal line.
9=30*25+25*53. which = 2975.
You have to split the shape into two smaller ones to make two rectangles and find the area of both and add them together.
With 12, you need to find the area of both shaped and subtract the triangle form the rectangle to get 93.5.
8) v=1/3 x 6^2 x 11
= 132cm^3
10) 80ft^3
11) 72km^3
