h = $\frac{5 \;-\;1}{4}$ = $\frac{4}{4}$ = 1
for x 1,2,3,4,5
Mid-ordinate are 1.5,2.5,3.5 and 4.5
y = 6x - x2
when x = 1.5
y = 6(1.5) - (1.5)2 = 9-2.25 = 6.75
x = 2.5,
y = 6(3.5) - (3.5)2 = 21-12.25
= 8.75
x = 3,5
y = 6(4.5)-(4.5)2 = 27 - 20.25
= 6.75
(for y ordinates)
area using mid-ordinate rule
=h(sum of ordinates)
= 1(6.75 + 8.75 + 8.75 + 6.75)
= 31 sq. units
