1.	(b) The perimeter of a triangle is 14 cm. The second side is 5 cm less than the first side and the thirdside is 3 cm more than the second side. The first side of the triangle is unknown.
Answer» let the second side be Xhence the first side is X+5third side will be X+3hence perimeter is sum of all sidesX+X+5+X+3=143X+8=143x=6X=2hence the first side is X+5=2+5=7cm
