Hey there! :)
Area of triangles → (base × height) ÷ 2
The base and height are the 2 legs. You have to find the length of the other leg to find the area, using the Pythagorean Theorem.
a² + b² = c² → c² - a² = b²
c = 12
12² = 12 × 12 = 144
a = 10
10² = 10 × 10 = 100
144 - 100 = 44
√44 = 6.6

Area of triangles → (base × height) ÷ 2
Base: 10
Height: 6.6
6.6 × 10 = 66
66 ÷ 2 = 33
The area is 33
Hope this helps :)

Answer:
34 2/3
Step-by-step explanation:
You need 47 yards. You have 12 1/3
47 - 12 1/3. So we'll break it down.
47 - 12 = 35.
Now, 35 + 12 1/3 would make 47 1/3
So now 35 - 1/3=34 2/3
34 2/3 + 12 1/3 = 47
