Question

The perimeter of triangle is 8cm. and one of its side is 3 cm. area of the triangle is maximum, find the other two sides

Answer 1

Let the other side be 2x
Then,3+2x=8
2x=8-3
x=5/2
x=2.5cm

|| PROOF||
THE PERIMETER OF TRIANGLE =SUM OF ALL ANGLES
THEN,(3+2.5+2.5)cm=Perimeter of triangle
8cm =perimeter (VERIFIED)
