Find the diagonal of a rectangle with 9 inches width and 6 inches length?
Using Pythagoras' theorem it is about 10.81665383 inches.
If the only known fact is the length of the diagonal then the width and length of the rectangle CANNOT be determined. The diagonal could be that of a square, or of a rectangle that is very long but quite narrow. Consequently at least one more fact is required such as; the dimension of either the length or the width, or the angle that the diagonal makes to the base of the rectangle or even…
The area of a rectangle is 56.25 square inches. The length of the rectangle is12.5 inches what is the width?
The area of a rectangle is length times width. If you have the length and a diagonal, you will first have to figure out the width, using the formula of Pythagoras. length2 + width2 = diagonal2; solving for width: width = square root of (diagonal2 - length2). Once you have the width, just multiply lenght x width.
What is The length of a rectangle is 3 inches less than twice the width. If the perimeter of the rectangle is 18 inches find the width of the rectangle?
A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.
