Help me solve for A and B!

6 0

Here we have one large triangle with two smaller triangles drawn inside. The two smaller triangles are similar.

Thus, a/12 = 12/16, or a/12 = 3/4, or 4a=36, or a = 9.

Find b in the same way: b/20 = 9/12 (and so on).

Answer:

<h2> A = 24.5 square units</h2>

Step-by-step explanation:

$J(-3,\,4)\ \ \implies\ y_J=4\\\\K(4,\,4)\ \ \implies\ y_K=4\\\\y_K=y_J\ \ \implies\ JK\parallel X{-}axis\ \implies\ H=|y_L-y_K|\quad\ \{for\ JK=base\}\\\\H=|-3-4|=|-7|=7\\\\\\ JK\parallel X{-}axis\ \implies\ B=JK=|x_J-x_K|=|-3-4|=7\\\\\\A=\frac12BH\\\\A=\frac12\cdot7\cdot7=24.5$
