It depends on what the shaded and non-shaded parts look like!
Base X Height - pi(r)^2
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
length times width
Area of what? Every geometrical shape has a different formula to find its area. The simplest one: to find the area of a rectangle whose edge lengths are h and w, area = h*w.
Base X Height - pi(r)^2
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.
The area formula for the parallelogram is related to the area formula for a rectangle because you can make the parallelogram into a rectangle to find the area.
If the base is a rectangle, use the formula for the area of a rectangle.
In the formula for the rectangle, put the width equal to the length.
You either need to find the area of the triangle and subtract it from that of the rectangle OR you find the areas of the bits of the rectangle that are outside the triangle and add them together. Without more details of the triangle, it is not possible to give a more detailed answer.
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.
Find the area of the shaded region means find the area of the area that is shaded in or darkened.
of course base times height for a square or rectangle. but for a trapezoid a= h x "b1+b2"
15.45-15.48 apex!!
The formula for the area of a square is simply L2 (sometimes referred to as s2 ) where L (s) is the length of one side. The formula for the area of a rectangle is LW, where L is the length and W is the width. The formula for the area of a rectangle can be used to find the area of a square, but the formula for the area of a square cannot be used to find the area of a rectangle. This is because by definition, all squares are rectangles, but not all rectangles are squares.
Typically, when a mathematical problem wants you to find the value of a shaded area, it wants you to calculate the area. If the shaded area is a circle, the area can be found by multiplying pi by the square of the radius. If the shape is a triangle, the area is base times height, divided by 2. If the shape is a square or rectangle, the area is length times width.
