The diagonal calculator measures the diagonal, area, perimeter, and diagonal angle of a rectangle. You just need to enter only two values to find the diagonal of the rectangle.
A Rectangle is a quadrilateral having four angles and all the angles are 90 degrees. The opposite sides of the rectangle are parallel and equal in length. The adjacent sides of the rectangle are different in length, but the diagonals are equal in length and intersect in the middle point of the rectangle. We need to enter the length and width in the rectangle diagonal calculator to find the diagonal of the rectangle.
We can find diagonal of a rectangle as:
Diagonal = √(l² + w²)
Where:
I = Length of the Rectangle
W = Width of Rectangle
We can find the Area of the Rectangle by multiplying the length and width:
Area = l× w
The perimeter of the rectangle can be measured by the given formula:
Perimeter = 2l + 2w=2(l+w)
We can find the diagonal of rectangle, area, and perimeter by the diagonal calculator.
We can encounter various possibilities to find diagonal of a rectangle.
First, we have to find the length by the given formula:
l= A /w
Then,
P = 2l + 2w
Diagonal length of a rectangle = √(l² + w²)
First, we have to find the width:
w= A / l
P = 2l + 2w
The diagonal measurement of a rectangle can be done as:
Diagonal = √(l² + w²)
w = (P – 2l) / 2
Area = l× w
Diagonal = √(l² + w²)
l= (P – 2w) / 2
Area = l× w
Diagonal = √(l² + w²)
Measure the length of the diagonal, area, and perimeter of a rectangle whose length is 4 units and width is 3 units.
Sol:
Length = 4 units
Width = 3 units
Substituting the values in the below equation
Diagonal = √(l² + w²)= √(4² + 3²) = √(25²).
The rectangle diameter = 5 units.
Length of diagonal of a rectangle= 5 units.
Area of rectangle = l× w
Area of rectangle = 4× 3 = 12 unit²
Perimeter of the rectangle = 2l + 2w
Perimeter of the rectangle = 2(4) + 2(3)
The perimeter of the rectangle = 8+ 6
The perimeter of the rectangle = 14 units
