Area of a rectangle is length times width.
It depends on which shape. For a circle: 3.14r2 For a square or rectangle: length x width
Find the area of each rectangle (length * Breadth) and add the results together.
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!
To find the perimeter and areas of complex shape without a grid you should divide the shape into simple shapes and find the area of each shape alone and then add up the areas all together to get the area of the whole shape. Example: If there is a shape that can be divided into 2 triangles and 1 rectangle then you will find the area of each triangle alone and then the area of the rectangle then add up all the areas together.
By using that one thing.
It depends on the shape of the area you are trying to find. The most basic calculation would be the area of a rectangle, which is A = lw (area = length times width).
The formula to find the area of a rectangle is: A = (length)(width)
Answer depends on what the shape is and what other information is available.
Depends on the shape of the area. For a rectangle the answer is the width * the height, assuming both measurements are in inches.
That will depend on the information given as for example if you are given its width and area then in order to find its length divide the width into the area.
