Answer 1

i got .6919 can you check please? @perl

Answer 2

so we have 5 rectangles
that gives us
delta x = ( 2 -1 ) / 5 = 1/5 = 0.2

so we want right endpoints,
area = .2 ( f(1.2) + f(1.4) + f(1.6) + f(1.8) + f(2.0)

Answer 3

area = .2 ( f(1.2) + f(1.4) + f(1.6) + f(1.8) + f(2.0)
= .2 ( .833 + .714 + .625 + .556 + .500)
