The area of a triangle is given by the formula A = (1/2)bh, where b is the base and h is the height. Since this is an isosceles triangle, the height will also be the length of one of the legs.
125 = (1/2)(14)(h)
125 = 7h
h = 17.9 ft
Therefore, each leg of the isosceles triangle would be approximately 17.9 ft long, rounded to the nearest tenth. So the answer is:
17.9 ft
125 = (1/2)(14)(h)
125 = 7h
h = 17.9 ft
Therefore, each leg of the isosceles triangle would be approximately 17.9 ft long, rounded to the nearest tenth. So the answer is:
17.9 ft
