The perimeter of an isosceles triangle is 14 cm. one of its sides is twice longer than another of its sides. find all sides of the triangle.

Triangle is isosceles , it means two sides of the triangle are equal

and perimeter = 14cm

Let the two equal sides = x cm each

One of its sides is twice longer than another of its sides.

It means Third side = 2x

Now perimeter - 14 cm

It means sum of all sides = 14 cm

So

x+x+2x = 14

4x=14

Divide both sides by 4

x= 3.5 cm

It means two equal sides are 3.5 cm each

and third side = 2(3.5) = 7 cm

So three sides of triangle are 3.5 cm , 3.5 cm , 7 cm

d) 48
