Question

The perimeter of a triangle is 50 cm. One side of the triangle is 4 cm longer than the smallest side and the third side is 6 cm less than twice the smallest side. Find the area of the traingle.

Answer 1

area of triangle. 2×l+b

Answer 2

Let the smallest side =x
other 1st side =x+4
other 2nd side=2x-6
ATQ
x+x+4+2x-6=50
4x-2=50
4x=50+2
4x =52
x=52/4
x=13
other 1st side=17
other 2nd side=26-6
=20
now, Appling herons formuls,

s=(a+b+c)/2

s=25

area = (25*(25-13) * (25-17) * (25-20))1/2

thusarea=20*(30)(1/2)...
