![]() So just enter the length of both sides in the given box and click on the calculate button, the rest will be measured. ![]() So use the Area of a Rectangle Calculator to calculate the area of a rectangle by just adding the length and width within seconds. Use this area calculator to easily calculate the area of common bodies like a square, rectangle, triangle, circle, parallelogram, trapezoid, ellipse, regular octagon, and sector of a circle. To calculate the rectangle area, use the formula below. We have designed this tiny handy calculator which is helpful to calculate the area of a rectangle. For instance, consider that you have to calculate the area of a rectangle that has a length of 3 meters and a width of 4 meters. The name comes from Latin rectangulus, that was created by combining rectus (meaning right) and angulus (meaning angle). It consists of 2 pairs of parallel sides. Program 1: User would provide the length and width values during execution of the program. The area of a rectangle simply measured by multiplying the dimensions of two adjacent sides or we can say it is the multiplication of width by the length. Rectangle Calculator Enter side length a and b Enter side length and diagonal length Definition Rectangle - a geometrical figure, any four sided figure with only right angles. In this tutorial we will see how to calculate Area of Rectangle. A rectangle is a basic shape with four sides, four vertices and four right angles. Check the scope of variable declare outside the main function and (l,b) both variables declare in a. Integrating curvatures over beam length, the deflection, at some point along x-axis, should also be reversely proportional to I.The area of a rectangle is the area cover inside the rectangle. GO Program to Calculate Area of Rectangle and Square. Therefore, it can be seen from the former equation, that when a certain bending moment M is applied to a beam cross-section, the developed curvature is reversely proportional to the moment of inertia I. Where Ixy is the product of inertia, relative to centroidal axes x,y, and Ixy' is the product of inertia, relative to axes that are parallel to centroidal x,y ones, having offsets from them d_. ![]() Want to know why this formula works Check out this. Where I' is the moment of inertia in respect to an arbitrary axis, I the moment of inertia in respect to a centroidal axis, parallel to the first one, d the distance between the two parallel axes and A the area of the shape (=bh in case of a rectangle).įor the product of inertia Ixy, the parallel axes theorem takes a similar form: To find the area of a rectangle, we multiply the length of the rectangle by the width of the rectangle. Divide the total area by the side measurement you know. The so-called Parallel Axes Theorem is given by the following equation: Calculate the unknown defining areas, diagonals and angles with any three known variables. The formula used to find the perimeter of a rectangle is P 2 (l + w) In the above formulas, A stands for area, P stands for perimeter, l refers to the length of the rectangle, and w refers to the width of the rectangle. The moment of inertia of any shape, in respect to an arbitrary, non centroidal axis, can be found if its moment of inertia in respect to a centroidal axis, parallel to the first one, is known. ![]()
