How to calculate the area of a rectangle a rectangle is a quadrilateral with two sides of equal length and two sides of equal width that contains four right angles to find the area of a rectangle, all you have to do. A rectangle is a quadrilateral with two sides of equal length and two sides of equal width that contains four right angles to find the area of a rectangle, all you have to do is multiply its length with its width if you want.
Example: sam cuts grass at $010 per square meter how much does sam earn cutting this area: let's break the area into two parts: part a is a square. Area is 2-dimensional: it has a length and a width area is measured in square units such as square inches, square feet or square meters to find the area of a rectangle, multiply the length by the width the formula is: a = l w where a is the area, l is the length, w is the width, and means multiply. Rectangle shape a = length side a b = length side b p = q = diagonals p = perimeter a = area √ = square root calculator use use this calculator if you know 2 values for the rectangle, including 1 side length, along with area, perimeter or diagonals and you can calculate the other 3 rectangle variables.

Parallelogram area = b × h b = base h = vertical height: trapezoid (us) sector area = ½ × r 2 × θ r = radius θ = angle in radians: note: h is at right angles to b: example: what is the area of this rectangle the formula is: area = w × h w = width h = height we know w = 5 and h let's break the area into two parts: part a is a. In words, the surface area of a rectangular prism is the area of the six rectangles that cover it but we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same the area of the top and bottom (side lengths a and c) = ac.
