The first thing you need to do is convert the yards into feet. In one yard there are three feet. So 2*3=6 now you can do the triangle area equation. 6*4.25=25.5 then divide by two. 25.5/2=12.75So the area of the triangle is 12.75 ft^2Hope this helps

Answer:

Height = 10.4The formula for finding the area of a triangle is (base/2) x height

Base =12

(12/2) x height=62.4

6 x height = 62.4

Height = 62.4/6

Height = 10.4

Step-by-step explanation:

The formula for finding the area of a triangle is (base/2) x height

Base =12

(12/2) x height=62.4

6 x height = 62.4

Height = 62.4/6

Height = 10.4
