A triangle has an area of 144 sq. inches and its base is 2 ft. long. What is the altitude of the triangle?
:
The area of a triangle: 1%2F2*b*h = area
:
Convert 2 ft to inches; 24"
:
Substitute for 144 for Area and 24 for b:
1%2F2* 24 * h = 144
:
2 cancels into 24 so you have
12h = 144
h = 144%2F12
h = 12 inches
:
:
Check solution:
A = .5*24*12
A = 144
