Question 626645
The area of square-shaped flower garden is 64m^2. It is surrounded by a walk of uniform width.
a.) how would you represent the length of one side of the walk?
Let w = width of walk
then each side is:
w + 8 + w
or
2w+8
b. )what expression represents the total area of the garden and walk?
(2w+8)(2w+8)
c.) if the walk is 15m. What is the area?
(2w+8)=15
2w = 7
w = 7/2
area then is:
(2w+8)(2w+8)
(2(7/2)+8)(2(7/2)+8)
(7+8)(7+8)
(15)(15)
225 square meters (area of garden and walk)
