What is the area of a square? Know the definition, formulas and solve the word problems here with us at BYJU'S. Get perimeter of square formulas also to solve more questions on the square.
We can clearly see that in the results section, we have got the same result as we did when we used the formula ourselves. This is not enough. We can also find the area of a square when we do not know the side but are aware of the length of its diagonals. Let us see how it wo...
Alternatively, the formula to calculate the area of a rectangle is derived by dividing the shape into two equal size right triangles. For example, in the given rectangle ABCD, a diagonal from the vertex A is drawn to C. The diagonal AC divides the rectangle into two congruent right angled ...
For example, if the length of the rectangle is missing, and we know the diagonal and width, then we can express the length in terms of the width and the diagonal and then use it in the formula of the area of a rectangle. We know that (Diagonal)2= (Length)2+ (Width)2. So this...
The formula for the area of a rectangle is the product of the length and width of the rectangle. The area of a rectangle is in square units. How do we calculate area? The area of a rectangle is calculated using the formula for the area of a rectangle. If the perimeter or diagonal va...
hence, the area of a quadrilateral formula is, \(\begin{array}{l}area\ of\ a\ general\ quadrilateral= \frac{1}{2} \times \; diagonal \times (sum \; of \; height \; of \; two \; triangle)\end{array} \) area of quadrilateral using heron’s formula we know that heron’s ...
Calculating the Area of a rectangle using the formula Here we have a rectangle, covered with small squares. Each small square stands for 1 square centimetre, that is, each small square is cm on each side. Count the number of squares that cover each rectangle. This will give you the area...
If the interior angles are equal, we have a square, whose diagonal is given by s x sqrt(2). What is the formula for finding the area of a rhombus? Let s, h, D, d, and a be the side, the height of the bigger and smaller diagonals, and one of the interior angles of a ...
