The theatre has 4 chairs in a row. there are 5 rows. Using rows as your unit of measurement, what is the perimeter.

18 rows.

Step-by-step explanation:

The theatre has 4 chairs in a row.

There are 5 rows.

If we consider rows as unit, then we observed that

Length = 4 rows

Width = 5 rows

Perimeter of Rectangle = 2(length +breadth)

= 2(5+4)

= 2(9)

=18 rows

Hence, the perimeter is 18 rows.

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

it’s supposed to be -4+45=41
