Question

if the perimeter of a triangle is 6and2by3cm and the lenght of two sides are 2and2by2 cm and 3and1by3 cm find the lenght of the third side?

Answer 1

Perimeter of a triangle is 6 2/3cm=20/3 cm

Length of 1st side is 2 2/3=8/3cm

Length of 2nd side is 3 1/3=10/3cm

Let length of 3rd side be x

Perimeter=length of 1st side+second side+third side

20/3=8/3+10/3+x

20/3=18/3+x

x=20/3-18/3

x=2/3cm
