The width of a rectangle is 20% of its length. If the area of this rectangle is 720 square inches, what is its length?

1 answer:

8 0

ANSWER: Length is 60 inches. AREA=LENGTH×WIDTH if your width is 20%of your length then you would multiply your length by 20%. So 60×20%=12. So now you just multiply 12 by 60 and get 720.

Looks good to me. Calculation is correct. Although you might want to add to #1 your description; that the width of the rectangle is the circumference of the circle (w = 2πr) and that you add the surfaces together to get the total surface area.
total surface area = area of rectangular part + area of circular parts
SA = 2πrL + 2πr²
