AREA OF A TRIANGLE

AREA OF A TRIANGLE:

Illustration 1:

Illustration 2:

FORMULA: A = 1/2 b*h

Where:

A = area

b = base

h = height

Example:

1. Find the area of a triangle whose base is 4 feet long with the height of 5 feet.

Given:

base = b = 4 ft.

height = h = 5 ft.

Solution:

A = 1/2 b*h

   = 1/2 (4 ft. * 5 ft.)

   = 1/2 (20 ft ²⁾

   = 10 ft ^{2 , final answer}

2. A triangle has the base measures 20 inches and 15 inches for the height.What is the area of the triangle?

Given:

b = 20 in.

h = 15 in.

Solution:

A = 1/2 b*h

   = 1/2 (20 in. * 15 in.)

   = 1/2 (300 in ²⁾

   = 150 in ^{2 , final answer}
