Henry plans to enclose a square garden with fencing. The area of the garden is 400 square feet. How many feet of fencing does he need to enclose the garden?

Question

This has something to do with powers, roots, and or exponents. This is what t says on the worksheet.

Answer 1

The shape of the garden (square) tells you that both the length and the width of the garden are the same measure. If the area is 400sqft, you can determine that side * side = 400. To find this answer, you can take the square root of 400. side=20, because 20 * 20= 400 (the area). Now, we know that each side measures 20 feet. Try drawing and labeling a picture to help you visualize the garden. Next, label each side of the square garden 20ft. How many feet of fencing is needed to enclose the garden? We need to add up the perimeter or we can do 20ft * 4 sides = 80 feet of fencing.
