Answer:
The amount Frances will spend to put a fence around his garden is $180
Explanation:
Fencing per foot is $10
To how the size of the total fence, we used the perimeter of a rectangle to get that which is 2(l + w)
where l and w are the length and width respectively
l = 5 feet, w = 4 feet
p = 2(5 + 4)
p = 2(9)
p = 18 feet
The cost of fencing 18 feet will be
18 × $10 = $180
