Find the area of a triangle with a base of 10 in. and an altitude of 14 in. (The formula for the area of a
triangle is A = bh รท 2.)
A. 140 sq in.
B. 280 sq in.
C. 70 sq in.
D.24 sq in.
Find the area of a triangle with a base of 10 in. and an altitude of 14 in. (The formula for the area of a
triangle is A = bh รท 2.)
A. 140 sq in.
B. 280 sq in.
C. 70 sq in.
D.24 sq in.
In this problem, altitude means height. So if, Area = bh/2 you can substitute in the values they give you.
Base = b = 10
Altitude = height = h = 14
A = bh/2 = 10*14/2 = 140/2 = 70. Choice C.
