Answer:
a = 4h.
Step-by-step explanation:
Area (a) = base (b) * height (h).
When h = 2, a = 8:
a = bh
6 = 2b
b = 4
The result 4 is the same for h = 5, 7 and 12.
So the required equation is
9514 1404 393
(b) 20 1/4
9(-3)^2(2^-2) = 9(9)(1/4) = 81/4 = 20 1/4
b
y=4.5x + 8

I got 224. 7(4)^2 = 112 •2 =224
