Find the altitude of the triangle if its area is 25 ares and base is 20 m.

Answer»

Area of triangle = 25 ares

We know that 1 are = 100 sq m

So, 25 ares = 25*100

= 2500 sq m

So, the area of the given triangle is 2500 sq m

Base = 20 m

Area of triangle = 1/2*Base*Height

⇒ 2500 = 1/2*20*H

⇒ 2500 = 10H

⇒ H = 2500/10

⇒ H = 250

So, the height or altitude of the given triangle is 250 m

Thank you

Area of triangle = 1/2 * Base (b) * Altitude (h) Both height and altitude are same in the case of triangle.

1 acre = 4046.85 metre sq.25 acres = 25 * 4046.85 = 10117.25 metre sq.

10117.25 = 1/2 * 20 * h 10117.25 = 10 *hh = 10117.25/10 = 1011.725metres

Therefore the altitude of the triangle is 1011.725 metres.
