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. |
