It is: 10*5*4 = 200 cubic m
200m dummies
40 cubic meters
5m-5n+5m+5n When simplified: 10m
4m+9+5m-12=42 9m=45 m=5
8*4*5 = 160 cubic metres.
Assuming these measurements are in pairs 10m x 10m is 100m2 6m x 4m is 24m2 7m x 3m is 21m2 Total 145m2
Rectangles are really simple. The perimeter is twice the length plus twice the width (in this case 4m x 2 = 8m, 5m x 2 = 10m, and 8m + 10m = 18m). The area is simply the length times the width (in this case, 4m x 5m = 20m2).
