A leather coin purse has the shape of a triangle. Two sdes are equal in length and the third side is 3 centimeters shorter than one and one-half times the length of the equal sides. The perimeter is 28.5 centimeters. find the lengths of the sides.
**
let x=length of one of the equal sides
1.5x-3=length of the third side
2x+1.5x-3=28.5 (perimeter)
3.5x=31.5
x=9
ans:
length of third side=10.5 cm
length of equal sides=9 cm
