The plot of land has the shape of a rectangle, the length of which is 4 m and the width is 10 dm less.

The plot of land has the shape of a rectangle, the length of which is 4 m and the width is 10 dm less. It is wired in 6 rows. How many meters of wire did it take

10dm = 1m
1) 4-1 = 3 (m) -width of the land
2) Now we will find the perimeter of the plot of land
P = (a + b) • 2
(4 + 3) • 2 = 14 (m) -perimeter of a plot of land and so much is required to enclose a plot of land in 1 row
3) 14 • 6 = 84 (m) – how much wire is required to enclose a plot of land in 6 rows
Answer: 84 meters
