17. Some parks contain fenced gardens. Suppose that it costs $80 to build each metre of fence, including materials and labour.
a) How much does it cost to enclose a square with an area of 120m²? express your answer to the nearest dollar.
B) Perdict whether the total cost of enclosing two squares with an area of 60m² each is the same as your answer to part a)
√60 = 7.75
7.75 x 4=31
31 x 80 = 2480
2480 x 2= $4960
The cost will not be the same.
