There is a rectangular shape of play-ground at the back of our school. The length of this playground is 40 metre and the breadth is 20 metre. A road having 3 metre with is there all around inside the play-ground. Let's work out how much money will be required to contruct the road at Rs. 95/sq.m.

There is a road of equal width around the outside of a rectangular play ground having the length 45 m and breadth 40 m and the area of the roda is 450 sq-m.

There is a road of equal width around the outside of a rectangular play-ground having the length a m and breadth b m and the area of the road is A square-metre. Find the required quadratic equation .

The length and breadth of a rectangular land are 20 metres and 14 metres. A hole of length 6 metres,. of breadth 3 metres and of depth 2·5 metres is dug in one corner of the land. If the soil of this hole be strewed upon whole land, then how much the height of the land should be increased ?

The height of chandmari road is to be raised , so, 30 cuboidal holes with equal depth and of equal measure are dug out on both sides of the road and with this soil the road is elavated .If the length and breadth of each hole are 14 m and 8m respectively and if the total quantity of soil required to make the road be 2520 cubic metre, then calculate the depth of each hole.

The depth of a cuboid pond with length of 20 m and breadth of 18.5 m is 3.2 m, determine the time required to irrigate whole water of the pond with a pump having the capacity to irriagate 160 kilolitres water per hour. If that quantity of water is poured on a paddy field with a ridge having the length of 59.2 m and breath of 40 m, then what is the depht of water in that land ? [Let 1 cubic metre=1 kilolitre]
