Answer:
24
Step-by-step explanation:
u can do mental math or use a calculator
P=2(l+w)
Substitute width plus 3 for length
Remember order of operations: multiply before adding
86=2((w+3) + w)
86=2w+6+2w
86=4w+6
80=4w
20=w
23=w+3=l
Check the answer
86=2((w+3) + w)
86=2((20+3)+20
86=2(23+20)
86=46+40
86=86
Then mark it down by less then 1%, of by whatever the number would be.
