An isosceles triangle has area of 125 ft. If the base is 16 ft, what is the length of each leg? Round your answer to the nearest tenth

Hey there! :D

Area= 1/2*base*height

We know the area and the base. We will solve for height. 

125= 1/2*16*h

Divide both sides by 2. 

62.5= 16*h

Divide both sides by 16. 

h=3.90625 

Round to the nearest tenth. 

h=3.9 <== the 9 is in the tenth place.

I hope this helps!
