How you figure the square yards really depends on the shape of the plot. I'll tell you how to do it for a rectangle. If you have a different shape, then you can get the arithmetic from the lawn and garden or hardware store. -- Measure the length, in feet. -- Measure the width, in feet. -- Multiply the two numbers. -- That gives you the number of square feet. -- For square yards, divide the number by 9 .

If the lawn is rectangular (or square) then measure its length and width - in feet. The area is length * width. If it is odd shaped, try and mark out rectangles, measure their area as above and then add together the answers for each rectangle.
use pythagorean's theorem... 152 + 82 = c2 c = 17 the length of the pipe will be 17 feet long
In order to answer that, you would need to know the configuration of the path, that is, where it goes. Does it provide a route down the center of the lawn's length ? Does it cut across the lawn's breadth ? Does it connect one corner of the lawn diagonally to the opposite corner ? Perhaps the path is immediately adjacent to the outline of the lawn, and takes you completely around it. In that case, the path is simply a long rectangle that has been bent into four straight segments and laid along the lawn's outer edge. If the rectangle were reassembled by laying the four segments straight in line again, it would be 2m wide, and equal in length to the distance around the lawn (the perimeter). Surely you would have no trouble calculating the area of that long narrow rectangle, if that were the path's configuration.

It depends on the shape. Let's say your lawn is 1 foot by 100 feet, which equals 100 square feet, then the surrounding measurement, called the 'perimeter', is 1+ 1+ 100+ 100 = 202 feet. Or, if the lawn is, say, 4 feet by 25 feet, which equals 100 square feet, the perimeter is 4+ 4+ 25+ 25 = 58 feet. If the lawn is perfectly square, its size would be 10 feet by 10 feet, and the perimeter is 10+ 10+ 10+ 10+ = 40 feet. The same is true for all dimensions in between: the perimeter changes as the shape of the lawn changes.

A squares area is equal to the the square of one of the side lengths. Therefore √196*4=56 yards.
15 square yards = 135 square feet. (To repeat this type of calculation, just multiply square yards by 9 to get square feet).

Walking along the outside from one corner to the opposite = 30 + 16 = 46 yards. Walking diagonally = sqrt(302 + 162) = sqrt(900 + 256) = sqrt(1156) = 34 yards. So it is 12 yards shorter.

If the lawn is twice as long as it is wide, and length times width is 288, then 3x = 288, or x = 96. The lawn is then 96 by 192 feet. This means that the perimeter is 576 feet (96 + 96 + 192 + 192).

Using Pythagoras' theorem:x2 = 152 + 82x2 = 225 + 64x2 = 289x = sqrt(289)x = 17 feet long.
