Question

An isosceles triangular field perimeter is 250m and each equal side is 100m . Find the area of the field (use√15=3.87)

Answer 1

Answer:

1st and 2nd side=100

3rd side = 250-(100+100)=50

area

semi p=250/2=125

area= underroot 125×(125-100)×(125-100)×(125-50)

25underroot 125×75=2420.61
