Question 993257
L-W= 5, therefore L= W+5
2L+2W= 100 Substitute:
2(W+5)+2W= 100
2W+10+2W= 100 Add the W and subtract 10 from both sides
4W= 90 Divide both sides by 4
W= 22.5 And the problem says the length is 5 more:
L= 27.5
Let's proof this:
2L+2W= 100
2(27.5)+2(22.5)= 100
55+45= 100
100= 100 We have the correct answer.
