Question

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

Answer 1

Solution :-

Area of the triangle = 25 ares

We know that 1 are = 100 square meter

so, 25 ares = 25*100

= 2500 sq m

So, area of the given triangle is 2500 sq m

Base = 20 m

Area of triangle = 1/2*base*height

⇒ 2500 = 1/2*20*H

⇒ 20H = 2500*2

⇒ 20H = 5000

⇒ H = 5000/20

⇒ H = 250

So altitude is 250 m

Answer.

Answer 2

Area of a triangle = 25 ares
Since, 1 are = 100 m²
So, 25 ares = 25x100 = 2500 m²
Hence, area of triangle = A = 2500 m²
base = b = 20 m
Altitude = h = ?
Solution:
Area of a triangle = 1/2 (b) (h)
2500 = (1/2) (20) (h)
2500 = (10) (h)
h = 2500/10
h = 250 m
Which is the required answer.
Thanks.
