Assume they are right triangles, find the other side of the smaller triangle
2(57/8) = 14.25 sq/ft: (.514.258=57).
Find the other side of the larger triangle, using corresponding sides in
similar triangles
14.25 = 24.9375
Find the area of the larger triangle
.514*24.9375 = 174.5625 sq/ft area of the larger triangle.
