Find the missing dimension of each triangle described height 14 inches area 245 inches Square

Amiraneli [1.4K]

Given:
Triangle
height 14 inches
area 245 inches square

Formula in finding the area of a triangle is:

Area = (height * base) / 2

The base is missing, so we need to compute its value using the given figures.

245 = (14 * b) / 2
245 * 2 = 14b
490 = 14b
490/14 = b
35 = b

The base is 35 inches.
