Answer:

120 ft^2

Step-by-step explanation:

10 times x equals 20  (x equals 2)

assuming the same rule applys to the left wall

6 x 2 = 12

12 x 20= 240   (this is for a whole square)

240/2 (because its basically a square cut in half) your answer is 120

Considering the height(h) of the larger triangle

6/10 = h/20
h = 6/10 x 20 = 12 ft

Area of the larger triangle
A = 1/2 bh = 1/2 x 20 x 12
A = 120 ft2

Therefore the area of the larger triangle is 120 ft2
