You could use an area calculation to determine how much space is unused or available.
For instance, you could measure the outside of your school and find its area. Then you could measure the perimeter of the school yard and find its area. Then you could subtract the two to find out how much area is available for recreation and parking.
You would find the area of the inside and outside shape (pretending that the inside shape was not in the outside shape). then, you would take the area of the outside shape and subtract the area of the inside shape.
you simply find the area of all of the shape then - the white are(the shape inside)YOU MUST TAKE-AWAY FROM 360 degrees as this is the whole areaexample:a square is 17 bu 12 then take-away that from the shape insidehope this is what you are talking about
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Shape of what ?
Answer depends on what the shape is and what other information is available.
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
Such as? If you can break the shape up into triangles you can find the area that way. Or, you can get into calculus-based equations if you have an equation for the random shape.
You times the length by width, to get the area of the 2D shape.
Fill in the blanks so that the shape makes a square and find the area of that. Then find the area of the shape you added. When you have both areas, subtract the greater from the smaller.
Of a square? (area/height=base) Of a triangle? ({area/height}/2=base) Or of some other shape?
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
To find the area, first divide the shape into regular, simple shapes. Then use formulas to find the area of the smaller, regular shapes. Lastly, add up all the smaller areas to find the area of the original shape.
