Theperimeter is the total of the lengths of the sides. In this case 5+40+5+40=90m
median = 29
Yes you can.
To find the area of a rectangle, when you only know the perimeter, you can just just break the sides down into two pairs of lengths. For example; if the known perimeter is 100, you can call the two short sides, we'll call those the width, 10 (x2=20) and the two long sides, we'll call those length, 40 (x2=80) 20+80=100... Now you know all the lengths of the sides, so the area formula is L x W = area or 10 x 40 = 400. Any rectangle with a perimeter of 100 will have an area of 400, no matter what the lengths are and the process works for any rectangle, you just have to break the perimeter length down into two pairs of lengths.+++That starts off right but is NOT the full method.'You need to know the ratio between its length and breadth. Then apply that ratio to half of the perimeter to find the length and breadth.'Try it:L = 4, B= 6 so P = 20 but Area = 4 X 6 = 24 square units.L = 2, B = 8 so P = 20 again BUT Area now = 2 X 8 = 16 sq. units.For any given rectangle perimeter, there is an infinite number of possible areas.For a quadrilateral, Perimeter-only works only for the Square, for which A = [P/4]^2 = [(P^2)/16]

Assuming length is the greater, 40 x 1; 20 x 2, 10 x 4 and 8 x 5
Different pools have different proportions.
To find the perimeter of the rectangle you add up all the sides. There are two lengths and widths for every rectangle, so you know the length is 40 meters x 2 = 80 meters. Perimeter is the total length of all the sides so you just minus 120 from the two lengths which is 80. So the width is 40, divide 2 (2 widths) = 20 meters. Width = 20 meters OR if they're asking for widthS then it'll be 40 meters, but they're not.

An infinite number. All you need is any right triangle where the product of the lengths of the two legs is 40.

A 40' by 40' lot will have an area found by multiplying the lengths of two sides, or squaring the length of a side. That's 40 x 40 or 402 which equals 1600 square feet.
It is: 4*10 = 40 units of measurements The area for a square is length squared. so if we have L2=100, then square root of 100 is length which is 10. The perimeter of a square is the distance around the square, and if we add 4 lengths (because all lengths in a square are the same), we get 10x4 which is 40.
2 x 18 2 x4
Length of rectangle is 18 units and its width is 2 units
1 metre = 100 centimetres Area = 100 x 40 = 4000 cm2 Area of each tile = 10x 10 = 100 cm2 Number of tiles required = 4000/100 = 40 tiles Alternatively, 10 tile lengths = 1 metre : 4 tile lengths = 40 cm Number of tiles required = 10 x 4 = 40
