Question

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 17 cm

long and 4 cm wide. The diameter of each circle is the width of the rectangle. What is the area of the
bookmark? Use 3.14 for it.
The area of the bookmark is
cm?

Answer 1

80.56

Explanation:

To find the rectangle area you just multiply its length by its width:

17 * 4 = 68

You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula:
`\pi*r^2`

Since the radius (r) is 2 and
`\pi` is 3.14, you have the following equation:

A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 (A is Area)

Sum the rectangle's area with the circle's area:

12.56 + 68 = 80.56

And vuoila! there's your answer.
