.
Let h = height of triangle
then
(1/3)h = base of triangle
.
Area of any triangle = (1/2)*base*height
.
24 = (1/2)(1/3)h*h
24 = (1/6)h^2
144 = h^2
take the square root of both sides:
12 feet = h (height)
.
base:
(1/3)h = (1/3)12 = 4 feet

Let represent the measure of the base. Then represents the measure of the height. The area of a triangle is the base times the height divided by 2, so:

Hi,
*Note: Area of a tringle is (1/2)b*h
Let x be the base, the 3x will the height
24m%5E2+=+%281%2F2%29x+%2A+3x
%2848m%5E2%2F3%29+=+x%5E2
16m^2 = x^2
4m = x
the base is 4m
checking or answer
(1/2)4m * 12m =24m^2
