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

Accepted Solution

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. 


Round to the nearest tenth. 

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

I hope this helps!
