find the perimeter of a rectangle with length 11cm and it's area is 99cm²​

Sagot :

Answer:

Explanation:

We know that the formula for finding the area of a rectangle is A=L*W.

Keeping that in mind, we can plug in what was given to us:

99 cm^2= 11 cm * W

To find the width, you just need to divide 11 cm on both sides, which should give you W=9 cm

Now just add: 9cm+ 9cm+ 11cm+11cm

and you should get 40 cm as the perimeter.
