Ineed with this question! i already have part c figured out but i'm having a hard time understanding a and
becky is building a square rabbit cage. the length and width are both 3 feet less than the square dog pen she built for her dog. the area of the rabbit cage is 25 ft.
 
a. using d to represent the side of the square dog pen, write an expression to represent the area of the rabbit cage.

b. use the expression and the given area to find the length of a side of the square dog pen.
since each side of the rabbit pen is 5ft (25 squared=5ft) add 3ft to each side because the dog pen is 3 ft bigger in length and width, equaling 8ft. the dog pen is 8ft by 8ft= 36ft


c. how many feet of fencing is needed to enclose the 4 sides of the rabbit cage? (show work)
the rabbit cage is a square, and the area is 25ft, which has a square room of 5. since there are 4 sides of the rabbit cage which will be fenced, multiply 5 (which is 25 squared) by 4 (the sides) equalling 20. there needs to be 20 ft of fencing to enclose all 4 sides of the rabbit cage. (thats my answer for part c )
