Question

Farmer Watson wishes to fence a rectangular plot of ground measuring 235 ft by 150 ft.

(a) What amount of fencing (in feet) is needed?

(b)What is the total cost (in dollars) of the fencing if it costs $1.69 per foot?

Answer 1

Perimeter = 2(length + width) = 2(235 + 150).

Cost = perimeter times $1.69
