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%.

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
