The width is 7 meters and the length is 13 meters

Step-by-step explanation:

The perimeter of a  rectangle sandpit is 40 meters.

Let the width be w units, then the length which is 1 meter less than twice it’s width becomes:

The perimeter of a rectangle is given by:

We substitute P=40 and the length in term of w to get:

We simplify to get:

Divide through by 2 to get:

Hence

30

step-by-step explanation:

idk

i hope i

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
