Question

the area of triangle is 2.5 hectare find the perpendicular if its base is 625 metre​

Answer 1

Answer:

80 metre.

Step-by-step explanation:

1 hectare = 10000 metre sq.

2.5 hectare = 10000 * 2.5 = 25000 metre sq.

area of a triangle = 1/2 base * height

area = 25000 metre sq.

base of triangle = 625 m

let perpendicular = X metre

According to question,

1/2 * 625 * x = 25000

625x / 2 = 25000

625x = 50000

x = 50000 / 625

x = 80

therefore, perpendicular of triangle = 80 metre.
