Question 353592
d) P=2L+2W, so we can easily find the width since it doesn't change by plugging in P=28 and L=6.5 and solving for W
28=2*6.5+2W
28=13+2W
15=2W
7.5=W So now we know what Width is.
a) The equation that expresses P in terms of L is P=2L+2W
b) P=2*40+2*7.5=80+15=95
c) 215=2L+2*7.5
215=2L+15
200=2L
100=L
