What is an Area Model?
a model for multiplication problems, in which the length and width of a rectangle represents the product.
Why you multiply l by b for calculating the area of rectangle?
You calcualte the area of a rectangle by multiplication as this finds the interior or area inside the rectangle. Calculating perimeter consists of adding the four lengths of the rectangle to find the border length.
Does it matter which dimensions you select for length and width when you find the area of a rectangle?
No. Because of the commutative law of multiplication, it makes no difference.
How do you find the length if you have the perimeter and the width?
Equation for perimeter of a rectangle: p = 2l + 2w or: p = 2(l+w) Solve any of the previous equations for the length.
How do you find length and width of a rectangle when peremiter is given?
You really can't unless you know something else about the length or width or even the area of the rectangle. You have 2 unknowns (length & width) & only one equation (perimeter). In order to find 2 unknowns you need 2 equations, that's why you need to know something else about the rectangle such as how the length & width are related to each or the area of the rectangle. Hope that helps.
What is measurement of area?
For a rectangle, this would be the multiplication of the two different length sides.

If the length (L) of a rectangle is 3 less than 4 times the width (W) of the rectangle which of the following equations represents the relationship between the length and the width of the rectangle?
The equation is: 4W-3 = L

The length of a rectangle is 3 inches less than twice the width If the perimeter of the rectangle is 18 inches how wide is the rectangle?
This involves solving a small system of equations. Let L represent length and W represent width. Our two equations are: I) L = 2W - 3 II) P = 2L + 2W = 18 since the perimeter of a rectangle is the sum of twice the length and twice the width. If we substitute 2W - 3 for L in equation II, then we get: 2(2W - 3) + 2W = 18, and simplifying the right hand side we get 6W - 6 = 18 if we add 6 to both sides we get 6W = 24, and dividing both sides by 6 we get W = 4. Now, if we plug this back into equation I, we have L = 2(4) -3 = 8 - 3 = 5. So the answer is: the length is 5 and the width is 4.
What is the square feet of 465.27 by 106 feet?
Apparently this is a rectangle with length 465.27 feet and width 106 feet. Area of a rectangle is length x width. In this case it would be 465.27 x 106 Do this multiplication and you will get the answer in square feet.
How do you find the length if you have the perimeter and the width?
Equation for perimeter of a rectangle: p = 2l + 2w or: p = 2(l+w) Solve any of the previous equations for the length.
What is the area of a rectangle with a base of 112 mm and a height of 30 mm?
Area of a rectangle is length x height In this case it is 112 x 30 square mm Do the multiplication and you will have the answer you need

What kind of operation do you need to calculate the are of a rectangle?
MULTIPLICATION area for a rectangle is A = L * W * H where, A = area of rectangle L = Length of rectangle W = width of rectangle H = height of rectangle The dimensions of a rectangle (L, W, and H) are interchangeable because they are being multiplied together and hence each side of the rectangle can be arbitrarily assigned to a dimension.
The width of a rectangle is one half its length The perimeter of the rectangle is 54cm What are the width and length of the rectangle?
The length of the rectangle is 18cm. The width of the rectangle is 9cm.
