Surface area of rectangle
– Among all the shapes with the same perimeter, a circle has the largest area. In the above figure, the area of the parallelogram is b × h. Divide the total by 2 and add this to your total of completely filled squares. Then go around the perimeter and add up all the squares that are more than full. Simply place an imaginary grid of 1 squares over the part, and count the whole squares. The height is the vertical distance between the base and the top. To effectively work out a complex surface area, as shown left. To find the area of a parallelogram, we use the formula b × h, where b stands for base and h represnts height. In the rhombus ABCD, we can calculate the area as follows: The formula to find the area of a rhombus is pq/2 where p and q are the two diagonals of the rhombus. We calculate the area of a circle by the formula π × r 2, where r is the radius of the circle and π is a constant whose value is 227 or 3.14Įxample: Area of the above circle = π × r 2 So, the area of triangle ABC = 1⁄ 2 × b × h In the triangle ABC, the base measures 6 units and the height measures 4 units. We find the area of a triangle using the formula 1⁄ 2 × b × h, where base (b) is the length of any one side of the triangle and height (h) is the perpendicular distance between the base and the top vertex of the triangle. Triangles could be of various types, like the equilateral triangle, isosceles triangle, and right-angled triangle but the formula for the area of all kinds of triangles is the same. The area of a square and a rectangle is the product of its two adjacent sides. Different shapes have a different formula for calculating the area. The colored region in each shape represents the area of the respective shape. The following are the steps to follow to solve this problem. Logic to Calculate the Area of Rectangle in C For finding the area of the rectangle we simply need to multiply length and breadth. There are several 2D shapes such as square, rectangle, circle, rhombus, and triangle. Then the area of the Rectangle is 100 Explanation: Area of rectangle is the multiply of length (L) and breadth (B) L20, B 5 So, L B 20 5 100. Area of any 2D shape is the size of the region enclosed within it.
