Upis 99 Details Mark has a rectangular fenced lot for exercising his llama. The lot is currently 60 feet wide by 80 feet long. He is going to double the length of all four sides of the lot. Which statement describes the new area of the lot? The area will be 2 times as large. The area will be 4 times as large. The area will be 3 times as large. The area will be 6 times as large.

Answer 1

We know that

The lot is rectangular.

Its wide is 60 feet.

Its length is 80 feet.

Mark is going to double the length of all four sides of the lot.

For the initial area, we have.

`A=80*60=4800ft^2`

Then, since he doubles its dimensions, the new area would be

`A=2\cdot80*2\cdot60=19,200ft^2`

Once we have both areas, we divide them.

`(19,200)/(4,800)=4`

Therefore, the new area is 4 times as large. The answer is the second statement.
