How to calculate area of a diagram?

Answer 1

To calculate the area of a diagram, you need to determine the shape of the diagram and apply the appropriate formula. Here are the formulas for calculating the area of common shapes:

1. Rectangle: The area of a rectangle can be calculated by multiplying its length (L) by its width (W). Area = L × W.

2. Square: The area of a square is obtained by squaring its side length (S). Area = S^2.

3. Triangle: The area of a triangle can be calculated by multiplying its base (B) by its height (H) and dividing the result by 2. Area = (B × H)/2.

4. Circle: The area of a circle is calculated using the formula A = πr^2, where π is a constant (approximately 3.14159) and r is the radius of the circle.

5. Trapezoid: To calculate the area of a trapezoid, you need to know both the lengths of its parallel sides (a and b) and its height (h). Then, you can use the formula: Area = (a + b) × h / 2.

6. Parallelogram: The area of a parallelogram can be calculated by multiplying its base (B) by its height (H). Area = B × H.

To apply these formulas, measure the necessary dimensions of the diagram using a ruler or appropriate measuring tool and substitute the values into the corresponding formula.
