Olga purchases a rectangular mirror (the shaded region) that fits exactly inside a frame. the outer perimeter of the frame measures 60 cm by 80 cm. the width of each side of the frame is 10 cm. what is the area of the mirror?

2,400cm^2

Step-by-step explanation:

This is quite an interesting question.

Now, we know the frame measures 60 by 80. We also know that the thickness of the frame is 10cm in length. Hence from the side of the mirror to the other side of the frame is 10cm.

We have the 10cm on each side of the frame. Making a total of 40cm and 20cm each allowance on the length and breadth of the mirror. The length and breadth of the mirror is thus 40cm by 60cm.

The area of a rectangle is L * B

The area of the mirror is 40 * 60 = 2,400cm^2

the y will be in still but your answer will be y x 3
