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
Factorise to (5z-1)(z-4) = 0
then put 5z-1 = 0 so 5z = 1 z = 1/5
z-4=0 z = 4
z = 1/5 and 4
