Question

*PLEASE ANSWER* If we decrease a dimension on a figure, how is the figure’s area affected? a.) The area decreases. b.) The area becomes 0. c.) The area increases. d.) The area remains the same.

Answer 1

For example, the area for a rectangle may be calculated using A = LW, where the length L is multiplied by the width W. This means that if you reduce L by 2, you will actually reduce the area by two times the width W, since (L - 2)W = LW - 2W.

Answer 2

Answer: A) area decreases

Example: we have a 2 by 3 rectangle with area of 2*3 = 6. If we cut the first dimension in half, then we have a 1 by 3 rectangle that has area 1*3 = 3. The area has decreased. To keep the area the same, we would have to increase the other dimension some specific amount.
