Evaluate the area of common shapes:
Rectangle Calculator:
Calculate the area of a rectangle with a length of 10 units and a width of 5 units:
Input the dimensions of the rectangle (length and width) into the Rectangle Calculator.
The result is the calculated area of the rectangle:
Area of Rectangle: 50 square units
Triangle Calculator:
Calculate the area of a triangle with a base of 8 units and a height of 6 units:
Input the dimensions of the triangle (base and height) into the Triangle Calculator.
The result is the calculated area of the triangle:
Area of Triangle: 24 square units
Trapezoid Calculator:
Calculate the area of a trapezoid with bases of 5 units and 8 units and a height of 4 units:
Input the dimensions of the trapezoid (bases and height) into the Trapezoid Calculator.
The result is the calculated area of the trapezoid:
Area of Trapezoid: 24 square units
Circle Calculator:
Calculate the area of a circle with a radius of 6 units:
Input the radius of the circle into the Circle Calculator.
The result is the calculated area of the circle:
Area of Circle: 113.10 square units (approx)
