Question

5. Find the altitude of a triangle whose base is 15 cm and area is 0.9 m².​

Answer 1

Answer:

Here's your answer mate ✌️

12cm

Step-by-step explanation:

Base of the triangle = 15 cm

Area of the triangle = 0.9 m²

= 90 cm²

Height of a triangle and altitude of a triangle are the same thing

Let height be 'x'

Area of a triangle = 1/2 × base × height

Therefore, 90 = 1/2 × 15 × x

Therefore, 90 × 2/15 = x

That is, x = 90 × 2/15

Therefore, x = 180/15

Therefore, x = 12

Hence, Altitude is 12cm
