Ratio of the sizes of the smaller triangle to the sizes of the bigger triangle is 15 : 35 = 3 : 7 = 1 : 7/3
Area of triangle = 1/2bh
Ratio of the area of the smaller triangle to the area of the bigger trfiangle is 1/2bh : 1/2(7/3b)(7/3h)
1/2bh : 49/9(1/2bh)
270ft^2 : 49/9(270ft^2)
The best approximation of the area of the larger triangle is 1,470 ft^2
