0.01x + 0.07y = 0.22
0.03x -0.05y = 0.14
x + 7y = 22
3x - 5y = 14
x = 22 -7y
3*(22-7y) -5y =14
66 - 21y -5y =14
-26y = - 52
y =2
x + 14 = 22
x= 8
Okay so here's what you do. The arrows mean the the sides are the same length so the > line is 20in. And then they cut this up into 2 triangles and a trapezoid. BUT If you look closely 1 of the Triangles and the Trapizoid make a Parallelogram. The formula for finding the area of a Paralellogram is just b*h. So then you just need to find the area of the other triangle which would be 8*20/2 (the formula is b*h/2 for triangles) and then you add those to answers together. (So it's 20*16+8*20)
