Make sure you know the length and width of the rectangle in the SAME UNITS ... both in inches, or both in meters etc. Then just multiply the two numbers ... Length x Width. The answer is the area of the rectangle.
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
For a rectangle, the formula is: area = base x height Fill in the items you know, and solve for the remaining item.
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
If the base is a rectangle, use the formula for the area of a rectangle.
The formula is for a square and rectangle is A=bh or A=lw
You take the formula for a rectangle, replace what you know, and solve for the remaining variable.
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.
For a rectangle, the formula is: area = base x height Fill in the items you know, and solve for the remaining item.
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
You must first calculate the width, using the formula for the area of a rectangle (plug in the numbers you know into the formula, and solve for width). Once you know this, you can plug in the numbers in the formula for a rectangle's perimeter.
Area of a rectangle: a = l * w
If the base is a rectangle, use the formula for the area of a rectangle.
The formula is for a square and rectangle is A=bh or A=lw
A = lw Area of a rectangle = length times width
In the formula for the rectangle, put the width equal to the length.
There is no "height" of a rectangle, unless it's a rectangular prism. Do you mean the length? If you have the area of the rectangle, the equation should be:A= L x WPlug in the area and the length and solve for the width, or plug in the area the width of the rectangle, and solve for the length.
