Problema Solution
side x if a triagle is 3yd longer than twice side y. side z is 3yd shorter than twice side y. if the perimeter of the triangle is 14yd. find the lengths of the three sides.
Answer provided by our tutors
x = 2y+3
z = 2y-3
so, x+y+z = 2y+3+y+2y-3
or 14 = 5y
so, y = 2.7 yd
x= 8.4 yd
z = 2.4 yd
