Abookmark is shaped like a rectangle with a semicircle attached at both ends. the rectangle is 14 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 π.

First you must find the area of the rectangle:

14 x 4 = 56cm^2

Then you must find the area of the semicircles:

Because there are two semicircles you need to find the area of one full circle.

n = pi
A =nr^2
A=n x 2^2
A=4n
A= 4 x 3.14
A= 12.56

Add the area together:

12.56 + 56
=68.56cm^2
