Answer:

System of equations

160 = 2W + 2L

W = L - 16

Solution to system of equations

W = 32 ft

L = 48 ft

Step-by-step explanation:

The width is 16 feet less than the length, so the appropriate equation for that is ...

... W = L - 16

Using this expression for W, we can substitute into the equation for perimeter:

... 160 = 2(L - 16) + 2L

... 160 = 4L -32 . . . . . . . collect terms

... 192 = 4L . . . . . . . . . . add 32

... 48 = L . . . . . . . . . . . . divide by 4

... W = 48 -16 = 32 . . . . find W using the relation with L

Length is 48 ft; width is 32 ft.

ive got like 6 more weeks of school left ur so lucky also have a great summer
