This rectangular calculator can help you calculate the area, perimeter, diagonal, length or width of a rectangle if you know the required dimensions.
How does this rectangle calculator work?
Depending on the dimension to be determined, this rectangle calculator uses the formulas explained here:
■ In case you select to solve for area (A) you have to provide the length (l) and the width (w) then:
■ If you want to calculate the perimeter (P) you have to input the length (l) and the width (w):
■ In case you try to compute the diagonal of the rectangle (d) then you have to input the same two figures (its length and width) then:
■ If you want to determine the length (l)then you have to know the width (w) and the diagonal (d) of the rectangle:
■ In case you want to estimate the width of the rectangle (w) then you have to specify its length (l) and diagonal (d):
