Part A:What is the area of the garden?(Hint- Area of a rectangle is L x W)
Part B:The owner of the garden wants to put a fence around the perimeter of the garden.Write an expression for the amount of fencing that the owner will need and solve to find the perimeter.

Answer 1

22x•28

Explanation:

Formula for area= l•w=a

2x-7•3x^2+4x

1. Gather your like terms

2. Gather you unlike terms

3. calculate

4. set equation up to find the answer

1.2x-3x^2+4x

2. 7•4

3.2x-3x^=18x+4x=22x

4. 7•4=28

5. 22x•28
