Answer 1

area of a rectangle = base times height
= 8 times 14
area of semicircle = (1/2)(r^2)pi
r = (1/2)diameter
diameter = 8 so r = 4
so area of semicircle = (1/2)(4^2)pi

total area = (area of rectangle) + (area of semicircle)
= (8*14) + (1/2)(4^2)pi
=

Answer 2

thats very hard o.o

Answer 3

first part was just explaining :P
