Answer:
Hi i think that the answer is A
Jason would has 66 coins in his piggy bank because 31+26+29=86-20=66 Hope I could help!!
A square has 4 sides of equa length
the perimiter is 4 times the side, or P=4s where s=length of 1 side
the area is length times witdth, but since the length=width, area=s² where s is the length of one side
so express A=s² in terms of P when P=4s
solve for s first in P=4s
P=4s
divide both sides by 4

subsitute

for s in the other eqaution



in terms of the perimiter, the area is
