A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 19 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.

Respuesta :

Answer:

Since we have two semi-circles we can say that we have a full circle. using the circle area formula we can say that

3.14*2^2 = 12.56 cm

Using the rectangle area formula we can say that

19*4 = 76 cm

Adding them both together is

12.56 + 76 = 88.56 cm

So the bookmark has an area of 88.56cm^2
