Question

The area of a triangle is 84.335 in2. The height of the triangle is 8.35 in. To the nearest inch, what is the length of the base of the triangle?

Answer 1

The formula to find the area of a triangle is:
A = 1/2bh
84.335 = 1/2 b(8.35)
168.67 = 8.35b
20.2 = b.

84.335 = 1/2 (8.35)(20.2)
84.335 = 1/2(168.67)
84.335 = 84.335

The base is 20.2 in.

Hope this helps =)
