Question 309158
You know that the formula for Area of a triangle is A=bh/2, where b=base and h=height.


In this question, let's make the base 15 ft. A=225 ft^2

Use the formula:

A=bh/2
225=(15)h/2
450=15h
h=30


So the height is 30. This makes a right triangle with legs 15 and 30. Use Pythag's theorem to find the hypotenuse.



15^2 + 30^2 = c^2
225 + 900 = c^2
c = 33.5 ft
