How do you divide length and width?
Divide the area by the length if you are given these two figures but not the width. For example, if a rectangle has an area of 20 square feet and a length of 10 feet, divide 20 by 10 to get a width of 2 feet. Multiply the length times 2 and subtract this figure from the perimeter, if you’re given these values.
What is the length of the object?

How to find the length of an object?
Object.keys returns an array containing all of the object keys (properties) which can come in handy for finding the length of that object using the length of the corresponding array.

What are the dimensions of length and width?
Length, width, and height are measurements that allow us to indicate the volume of geometric bodies. T he length (20 cm) and the width (10 cm) correspond to the horizontal dimension. On the other hand, the height (15 cm) refers to the vertical dimension.
How to calculate the area of a shape?
Also a graphic will be shown of a scaled drawing to the correct proportions and labelled with each dimension and calculated area. Formula. The formula used by this calculator to calculate the area of a rectangular shape is: A = L · W. Symbols. A= Area; L = Length; W = Width; Area Dimensions – Length & Width
How to get the size of a JavaScript Object?
Object.size = function(obj) { var size = 0, key; for (key in obj) { if (obj.hasOwnProperty(key)) size++; } return size; }; // Get the size of an object var size = Object.size(myObj); There’s a sort of convention in JavaScript that you don’t add things to Object.prototype, because it can break enumerations in various libraries.
