| The lateral side of an isosceles triangle is 3 times the base. the perimeter of the triangle is 63cm. Find the sides of the triangle.
Let x cm – lateral sides of an isosceles triangle;
Then 3x is the base of an isosceles triangle;
We get the equation for the perimeter:
x + x + 3x = 63 cm;
5x = 63 cm;
x = 63/5;
x = 12.6 cm – the sides of the triangle;
3x = 12.6 * 3 = 37.8 cm – the base of the triangle.
