Direction: Isosceles triangles were used to construct a bridge in which the base (unequal side) of an isosceles triangle is 4 cm and its perimeter is 20 cm.




Q. If the sides of a triangle are in the ratio 3 : 5 : 7 and its perimeter is 300 m. Find its area.

  • a)
    100√2 m2

  • b)
    up>(b) 500√2 m2

  • c)
    1500√3 m2

  • d)
    200√3 m2

Correct answer is option 'C'. Can you explain this answer?

Let the sides of a triangle are a = 3x, b = 5x, c = 7x
Then a + b + c = 300
3x + 5x + 7x = 300
15x = 300
x = 20
So, a = 60, b = 100, c = 140
= 300/2 = 150
Area of triangle =
