Question

Krista wants the pen 5 feet long by 4 1/2 feet wide to be 4 times the area that it is now , what are the two ways she could change the lengthened or width give her that new area to be 4 times the area it is

Answer 1

I belive its 15

Hope this helped.

Answer 2

90ft^2

Explanation:

If she was trying to make it 4 times bigger is multiply the length or the width by a factor of 4

If the starting measurements were

5ft long and 4 1/2 feet wide you simply multiply the two

5 x 4.5 = 22.5 ft

Then when trying to make it 4 times bigger multiply your answer by 4

22.5 x 4 = 90ft^2
