Sarah wants to paint three walls in her family room. Two walls are 18 feet long by 10 feet
wide. The other wall is 12 feet long by 7 feet wide. What is the total area of the walls Sarah
wants to paint?

The total area is 444 ft².

Step-by-step explanation:

First you multiply 18 by 10 for one of the walls you get 180*2 since you have two walls with the same dimension. Next you do 12*7 to get 84. Last you would add 84 to 360 and get 444 ft²

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.
