Hi,
width of a certain rectangle is 5 inches more than one-fourth of its length
Let x and (.25x + 5in) represent the length and width respectively
Question states***
2(x) + 2*(.25x+5in) = 80in
Solving for x
2.5x = 70in
x = 28in, the length. the width is 12in (.25*28in + 5)
CHECKING our Answer***
2*28in + 2*12in = 80in
