Rectangle Diagonal Length

Calculation

Once you enter the input values in the calculator, the output parameters are calculated.

Examples

The following examples cover how to calcualte the Diagonal Length when length, and width are given.

1. What is the Diagonal Length of Rectangle whose length is 3 units, and width is 4 units?

Answer

Given:

  • length, l = 3 units
  • width, w = 4 units

The formula to find the Diagonal Length of a Rectangle is:

d = \({\ \sqrt{ l ^2 + w ^2}\ }\)

Substitute given values in the above formula.

d = \({\ \sqrt{3^2 +4^2}\ }\)

d = 5 units

∴ Diagonal Length, d = 5 units

2. What is the Diagonal Length of Rectangle whose length is 3 units, and width is 7 units?

Answer

Given:

  • length, l = 3 units
  • width, w = 7 units

The formula to find the Diagonal Length of a Rectangle is:

d = \({\ \sqrt{ l ^2 + w ^2}\ }\)

Substitute given values in the above formula.

d = \({\ \sqrt{3^2 +7^2}\ }\)

d = 7.62 units

∴ Diagonal Length, d = 7.62 units
