Question

The height of a triangle is 4000mm and is 12m2. Find the base of the triangle in m.

Any one that answers I will mark as brilliant

Answer 1

Base of triangle = 6 m

Explanation:

Height of triangle (h) = 4000 mm = 4 m

Area of triangle = 12 square m

`Area \: of \: triangle = (1)/(2) * b * h \\ \\ 12 = (1)/(2) * b * 4 \\ \\ 12 = b * 2 \\ \\ b = (12)/(2) \\ \\ b = 6 \: m`

Answer 2

Base is 6 m or 6000mm or 600cm

Explanation:

A meter is 1000 mm or 100cm

The height of the triangle is 4 meters

The area of the triangle is 12 meters²

The formula for the area of a triangle is:

`(1)/(2) *b*h`

`(1)/(2) *b*4 = 12\\`

Divide both sides by 4

`(1)/(2) *b=3`

Multiply both sides by 2

`b=6`

The base of the triangle is 6
