Solution:

The perimeter of rectangle is given as:

P = 2(length + width)

From given,

length = ?

width = 55 feet

perimeter = 290 feet

Therefore,

290 = 2(length + 55)

Thus length of rectangular lot is 90 feet

Solution:

Given equation is:

To find: y when x = -2

Substitute x = -2

Thus y is -9 when x is -2
