Area = length x width
get the area for each plot first.
the given is 3.67m long and 2.54m wide
then it will be written as 3.67x 2.54 = 9.3218 sq.m for each plot. the problem says that joy wants to make 6 garden plots. so just simply multiply the area of each plot which is 9.3218 x 6 plots = 55.9308 sq.m
