Question

a field is in the form of a triangle if its area is 2 ham and the length of its base is 200 m then find its altitude if 1 ha = 10000 sq m

Answer 1

area of triangle=1/2 BH

1 ham=10000 sq m

2 ham=20000 sq m

20000 sq m=1/2x200xh

100h=20000 sq m

h=200m

Answer 2

Let the altitude be h metres
area of field = 2 ha= 2×10000sq. metres = 20000 sq. metres
ATQ
1/2 × base × altitude = area
1/2 × 200× h= 20000
100h = 20000
h = 20000/ 100
h= 200m
