2w^2 + 2l^2 = 648. So we have w^2 + l^2 = 324.
The diagonal is sqrt(w^2 + l^2) = sqrt(324) = 18.
Since a diagonal divides a rectangle into two triangles, this is actually a problem in trigonometery. Since a rectangle has right angles, the resulting triangles also have right angles, therefore you can apply the Pythagorean Theorem. Or, just take your ruler and measure the diagonal. That's the direct approach.
The one alternative to find the area of a rectangle is when you are given the length of one diagonal and its slope.
The square of the diagonal minus the square of the height would equal the square of the width. Therefore the square root of the solution to the above problem would be the width
It is not clear what you mean by an incomplete rectangle. If it means the rectangle is not closed then there is a problem of defining its area: what is inside and what is outside when you do not have a boundary?

in this problem solving in a rectangle width is 3 and the perimeter is 16 what is he length
Designate the length by L. From the Pythagorean theorem, the length of the diagonal of a square, which divides the square into two right triangles, each with sides L (and the diagonal as hypotenuse to each right triangle), is square root of 2L2 = 4 (from the problem statement). Squaring both sides separately yields 2L2 = 16 or L = square root of 8 = 2 (square root of 2).
Measure it with a ruler or a compass. Also, if this is a purely theoretical problem and you have no actual square to measure, remember that the diagonal line cuts the square into two right triangles, which therefore can be analysed by the use of the famous Pythagorean Theorem.
If the perimeter is 32 sq cm, there is a very serious problem since the perimeter is a linear measure, not an area! Leaving that aside, the length of the rectangle is 10 cm and the breadth is 6 cm.
Doesn't describe the problem well enough.
37.2 cm Method: The two sides of your screen and the diagonal form a right angled triangle. So you can use trigonometry to solve the problem. One of the trigonometry rules is Pythagoras Theorem, which says; h2 = a2 + b2 Where h is the length of the diagonal (or "hypotenuse"), and a and b are the lengths of the other 2 sides. So we have; h2 = 302 + 222 = 1384 h = square root of 1384 = 37.2 cm
An oblique line (line that slants) from one part of the shape to the other e.g from one corner of a square to the opposite corner is a diagonal line. I hope this solved your problem
The answer depends on what the problem is: are you required to find the lengths of the missing sides, the area, angles, length of diagonal, or WHAT!
