Rectangle Area Calculator tool is used to calculate area, perimeter and length of the diagonal of a rectangle.
A rectangle is a 2D shape in, having 4 sides and 4 corners. Its two meet at . Thus, a rectangle has 4 , each measuring 90 ̊. The opposite sides of a rectangle have the same lengths and are parallel. Two sides are said to be parallel, when the distance between them remains the same at all points.Area of Rectangle
Area of rectangle is the product of Length and Width; Area A = L X W or A = a x b.Perimeter of Rectangle
The perimeter of a rectangle is the sum of its four sides. Since a rectangle has two equal short sides (width, b) and two equal long sides (length, a), perimeter=2a + 2bLength of the Diagonal
A diagonal of a rectangle cuts the rectangle into two right triangles with sides equal to the sides of the rectangle and with a hypotenuse that is the diagonal. By using Pythagorous theorem, we can easily find the length of the rectangle.
Length of the Diagonal=sqrt(Length2 + Width2)
