What is the area of a rectangle that has a perimeter of 61.18 cm and a diagonal of 226.1 mm showing key stages of work?

The area of rectangle is : 13832.797999999999


What is the area of a rectangle that its perimeter is 39?

156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.


What is the perimeter of a rectangle which has a diagonal of 8.50 cm and an area of 3000 square mm showing work with answer?

Here is what you are supposed to do: * Convert to consistent units. For example, convert the cm to mm. * Write an equation for the diagonal (in terms of length and width). Replace the known diagonal. * Write an equation for the area, in terms of length and width. * Solve the two equations simultaneously. * Calculate the perimeter.


How do you write an expression for perimeter of a rectangle that's length is 2x-7 width is x and the diagonal is 3x?

6x-14


How do you find the width and length of a rectangle if you only know the diagnol?

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 the rectangle.

What is a perimeter of a recangular?

Perimeter is Length + width x 2 or Length + length + width + width. This is perimeter for any shape including a rectangle. Perimeter of a rectangle is all sides added together for a rectangle.
