There are 3 different pairs of rectangles—the side rectangles, the rectangles on the top and bottom, and the other side rectangles.
10x11=110
110x2=220
15x10=150
150x2=300
15x11=165
165x2=330
330+300+220=850 m².
2 7/9 is A. real number
x = 9 m
y = 1 m
6/1 = x/1.5
x = 1.5 × 6
x = 9
6/1 = 6/y
6y = 6
y = 1
