Question

1.Write a function rule for the area of a rectangle with a length of 3 ft. more than two times it’s width. What is the area of the rectangle when its width is 4 feet?

Answer 1

`A = (w)(2w+3)`

or


`A = 2w^(2) + 3w`

When w = 4 feet


`A = 2(4)^2 + 3(4)`


`A = 2(16) +12`


`A = 32 + 12 = 44` feet
