A square plywood platform has a perimeter that is 6 times the length of a side, decreased by 6. Find the length of a side. (Recall the formula P = 4s.)

Question

anonymous · Answer

initial perimeter will be p1=4s when side is s
now side has decreased to (s-6) now perimeter isp2= 6s

so equate both the perimeters
p1=p2
 
4s=6(s=6)
 
4s=6s−36
 
2s=36
 
s=18

so the side will be 18.

in that not the aanswer this shoulld be P = 4s = 6s-6 6 = 2s
s =3
