Question

15. 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 ÷ 2.)

A. 280 sq in.
B. 24 sq in.
C. 70 sq in.
D. 140 sq in.

Answer 1

Base = 10 inches
Height = 14 inches

(Base x Height) ÷ 2 = Area
(10 x 14) ÷ 2 = Area
(140) ÷ 2 = Area
70 = Area

Area = 70 square inches

Answer 2

Hello There!

We know that the formula of a triangle is "Base Multiplied By Height And Then Divide It By 2"

First, let's plug in our numbers. Our base is going to be 10 inches so we have 10 multiplied by our height which is 14 inches and we get a product of 140.

Next, we divide 140 by 2 to get a quotient of 70.

Finally, our answer is 70in squared
