Question

the ratio of the height of a triangle to its base is 2:3. If the height of the triangle is 18cm, what is the length of the base

Answer 1

27 cm

Explanation:

Hi there!

Let b be equal to the length of the base.

Form a proportion:

`\displaystyle (2)/(3) =(18)/(b)`

Cross multiply:

`3*18=2b\\54=2b\\b=27`

Therefore, the length of the base is 27 cm.

I hope this helps!
