If in a square land the length of diagonal is 20√2 meter, let us write by calculating that how much length in meter is required for fencing a wall surrounding of it.

See the following figure and find out the perimeter.

See the following figure and find out the perimeter.

The rectangular land of Pritam has 5 meter wide path all around it on the outside. The length and width of the rectangular land are 2.5 dkm and 1.7 dkm respectively. Let us write by calculating that how much cost will be required for fencing around the outer side of path at the rate of Rs. 18 per in meter.

Let us see the card below, find perimeter and let us write by calculating what will be the length of one side of equilateral triangle with same perimeter.
