Question

A rectangular backyard garden has a width that is 4 feet wider that its length. A polynomial is created to find the area of the garden, A=l2+4l. The polynomial representing the area of the garden has a degree of _[blank]_. Enter the value which correctly fills in the blank in the previous sentence, like this: 42

Answer 1

A rectangular backyard garden has a width that is 4 feet wider that its length

let the Length of the garden is 'l'

Width is 4 more than the length so width is l + 4

Area of rectangle = length * width

= l * (l+4)

= $l^2 +4l$

Degree is the exponent so the area of the garden has a degree of 2

Answer is 2
