The length of a rectangle field is twice its breadth. Its perimeter is 400m. How do I find the length and breadth?

For the perimeter, add the four sides together and simplify. For the area, multiply the length by the width.

You can change a field name by right-clicking a value of the field in the pivot table > select Field Settings > and enter a new name in the "Custom...

Divide the area by the length, giving you the width. Add twice the width to twice the length.

Let x = the width. Then the length is 2x - 7. The perimeter is twice the width plus twice the length: 64 = (2x) + 2(2x - 7) =...

Such a rectangle would have its sides and diagonal in the ratio of 2:1:√5 (per the Pythagorean theorem). The ratio of √5 to the diagonal (20) is equal to the...

Use the Pythagorean Theorem to find the other side. Then multiply the length by the width.

You can't. With any given perimeter, an infinite number of length-width combinations would be possible.

Double the width, and subtract that from the perimeter. Then divide that number by two, which gives you the length of the rectangle. Then, multiply the result by the width...
