What is the sum of interior angles of a 22-gon?

No. of sides = 22
Let n be 22
Sum of interior angles = (n-2)180
                                      = (22-2)180
                                      = 20*180
                                      = 3600
I hope it is helpful:D

You can find the area of a rectangle by multiplying the length and height. so multiply 1/2*7/4(which is the simpler version of 1 3/4) and you get 7/8 as your answer.
