5th grade. what is the area of the triangle?

The area of a triangle is 1/2 bh. First, you add 24+37+3. Your answer is 64. Now you are gonna find 1/2 of 64, which gives you your answer of 32.

Area of the triangle=
1/2×B×h where B equal Base, and h equal height. For this problem, we see that the base equal 24 inches, but we do not have the height of this yet, so we need to find by using Pythagorean theorem, and I don't know that 5th grade learn that yet. This formula that I will let you know is 8th grade math.

a^2+b^2=c^2
(24/2)^2+b^2=37^2
144+b^2=1369
b^2=1369-144
b^2=1225
Square root this equation to get
b=35, and we know that the height will equal to 35 inches.

A=1/2×B×h
A=1/2×24×35
A=12×35
A=420 in.^2. As a result, the area of the triangle is 420 square inches. Hope it help!
