Question

In an isosceles triangle, the length of equal sides exceeds that of the base by 4.5cm. The perimeter of the triangle is334.5cm. Find the sides of the triangle.

Answer 1

let lenth of equal side to be x
so. base=x-4.5
a/q , perimeter of triangle =sum of all side of
triangle
334.5=x+x+x-4.5
3x=334.5-4.5
3x=330
x=110
so. side of the triangle is 110 cm, 110 cm and base is 105.5 cm
