Question

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

Answer 1

Answer:

Base of triangle = 6 m

Step-by-step explanation:

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

Area of triangle = 12 square m

$Area \: of \: triangle = \frac{1}{2} \times b \times h \\ \\ 12 = \frac{1}{2} \times b \times 4 \\ \\ 12 = b \times 2 \\ \\ b = \frac{12}{2} \\ \\ b = 6 \: m$

Answer 2

Answer:

Base is 6 m or 6000mm or 600cm

Step-by-step 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:

$\frac{1}{2} *b*h$

$\frac{1}{2} *b*4 = 12$

Divide both sides by 4

$\frac{1}{2} *b=3$

Multiply both sides by 2

$b=6$

The base of the triangle is 6
