There is a rectangle abcd. the length of the rectangle is increased by 10%.the width of the rectangle is increased by 5%,what is the percentage increase in the recatangle.

Therefore the area of rectangle is increased by 15.5%.

Step-by-step explanation:

Assume the length and width of the rectangle be x and y respectively.

The area of the rectangle is = length×width

                                               =xy.

Now the length of the rectangle is increased by 10%.

Then the length of the rectangle increased = .

New length of the rectangle is

The width of the rectangle is increased by 5%.

Then the width of the rectangle increased = .

New length of the rectangle is

New area of the rectangle is =

                                               = 1.155 xy.

The percentage of area increase is

=15.5.

Therefore the area of rectangle is increased by 15.5%.

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 .
