Explanation:

Given

See attachment for corner shelf

Required

The area

The corner shelf is a quadrant with radius;

`r = 8.5in`

The area of a quadrant is:

`Area = (\pi r^2)/(4)`

So, the area of the corner shelf is:

`Area = (\pi * 8.5^2)/(4)`

`Area = (\pi * 72.25)/(4)`

`Area = \pi * 18.0625`

Take
`\pi` as 3.14

`Area = 3.14 * 18.0625`

`Area = 56.7` -- approximated
