Question

The table below shows the base and height of three triangles in centimeters. Which triangles have the same area?

= 1/2 ℎ

Answer 1

Triangle 1 and triangle 3 have same area.

Explanation:

Given:

Triangle Base Height

1 30 16

2 60 40

3 20 24

Find:

Same area triangle

Computation:

Area of triangle = (1/2)(b)(h)

Area of triangle 1 = (1/2)(30)(16)

Area of triangle 1 = 240 unit²

Area of triangle 2 = (1/2)(60)(40)

Area of triangle 2 = 1200 unit²

Area of triangle 3 = (1/2)(20)(24)

Area of triangle 3 = 240 unit²

So,

Triangle 1 and triangle 3 have same area.
