Figure it like this:
Because each side of the rectangular plot will have a one-meter wide sidewalk adjoining it, you know that the sidewalk, on each side of the plot will be two meters longer than the plot's dimensions. However, if you figured the length by adding the areas of each length of sidewalk, you would be wrong, because each length of sidewalk shares two corners with the adjacent lengths. Each corner is one square meter, and each length of sidewalk without two corners is the same as the dimension of the plot, times one meter. So essentially, you just add the plot dimensions and then add four. In other words, 2(13m * 1m) + 2(20m * 1m) + 4m2 = 26m2 + 40m2 + 4m2 = 70m2.
Another way to figure it would be to figure the area which will be enclosed by the outer edge of the sidewalk (again, two meters longer than the plot on each side), and subtract the area of the plot itself, or: (15m * 22m) - (13m * 20m) = 330m2 - 260m2 = 70m2.

1m2 of half brickwall required around 0.03m3 cement mortar
1000 kg = 1 ton
0.3 cubic meter cement mortar consumes.
For M10 (1:3:6) Grade of concrete cement bag consumed = 4.4 bags/cum M15(1:2:4) Grade of concrete cement bag consumed = 6.6 bag/cum M20(1:1.5:3) Grade of concrete cement bag consumed = 8.2 bag/cum
On regular cement in spring or faill it won't. It depends too, if there is stuff on the cement sidewalk. Plus, if your talking but soild cement or in process of becoming hard. Cement in the winter like a sidewalk might be too cold depending on the temp outside. In the summer, the cement might be too hot and burn your dog's paw. Depends on the temp outside...
Sidewalk and driveway cement normally refers to concrete.
It is illegal to write in wet sidewalk cement in some cases. This is the case if the wet cement is government property.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
No, cement is a heterogeneous mixture.
No. Cement is a mixture of several elements and water. Hydraulic cement is made from limestone, clay, and gypsum.
To build a cement sidewalk, yes. But if you wanted to make a sidewalk out of something else, you could. My aunt used to have wooden sidewalks on her farm. Some areas just have dirt sidewalks, but it is still a sidewalk because it is still actually a place off the road where you are meant to walk.
Cement changed people lives because it help us make sidewalk and other stuff the evovles cement
The cement is grey due to the presence of iron oxide.The cement is white due to the absence of iron oxide.Generally white cement has more strength than grey cement and it is more expensive.

The separation between squares of sidewalk cement is usually referred to as a crack, although I think that gap might be more accurate.
The darker the color of the road the more sunlight it absorbs. A white cement sidewalk is whiter which absorbs many of the colors making it cooler.
