6. (a) Using the fact that the area
A
of a rectangle is width
×
length, we find
A
total
=(3
.
00 acre) + (25
.
0 perch)(4
.
00 perch)
=(3
.
00 acre)
(40 perch)(4 perch)
1acre
+ 100 perch
2
=580pch
2
.
We multiply this by the perch
2
→
rood conversion factor (1rood
/
40 perch
2
) to obtain the answer:
A
total
=14
.
5 roods.
(b) We convert our intermediate result in part (a):
A
total
=(580perch

)

=1

Now, we use the feet
