Question

1. The area of a triangle is 90 cm. If its base is 15 cm, find its altitude​

Answer 1

Answer:

Step-by-step explanation:

1/2 * b * h = 90

15 * h = 180

h = 180/15 = 12 cm

Answer 2

Answer:

Height of the triangle is 12cm

Step-by-step explanation:

As altitude of any triangle is its height.

So we have its base = 15 cm

and area = 90

So by area formula,

=> Area = ½ × base × height

=> 90 = ½ × 15 × h

=> h = 90/½×15

=> h = 12 cm

So, Height of the triangle is 12cm.
