Perimeter of a rectangle: 2(l+w)
Let width be 'x'
Length is 3 meters more than twice 'x'
Length= 2x+3.
L= x
W = 2x+3
Formula =
2(x+2x+3)
2(3x+3)
6x+6.
6(x+1)

(a)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
Now, the midpoints of these subintervals are:
Hence:
(b)
n=4, so :
Each subinterval has length :
Therefore the subintervals consist of:
[1,5], [5,9], [9,13]
The endpoints of the subintervals consist of:
5,9
Hence:
