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 perimeter is the sum of all four sides, so you need to calculate 2 x length + 2 x height. The fact that the rectangle is at the bottom of a triangle is irrelevant - except that in specific diagrams, information may be provided that lets you calculate the length or the width of the triangle.
To calculate the area of a rectangle you need to multiply the width by the length
A rectangle is a parallelogram but a parallelogram need not be a rectangle and so they are not the same.
To calculate the total number of tiles needed to make a rectangle that is 4 tiles wide, you would need to consider the length of the rectangle as well. If the length of the rectangle is x tiles, then the total number of tiles needed would be 4 times x, which simplifies to 4x. Therefore, the number of tiles needed to make a rectangle that is 4 tiles wide would be 4 times the length of the rectangle.
Well, sweetie, a rectangle doesn't have a diameter because that's a term reserved for circles. If you want to find the dimensions of a rectangle, you measure the length and width, honey. Just grab a measuring tape and get to work, no need to overcomplicate things.
no No. You need to know the length of a rectangle's sides in order to calculate the perimeter.
The perimeter of a rectangle is the distance around the rectangle. The area of a rectangle is the space inside the rectangle. To calculate either one you need the length and the width of the rectangle. To calculate the area multiply the length times the width. To calculate the perimeter add the length+width+length+width (that is the distance all the way around)
You need two dimensions to calculate the area of a rectangle. Area = length multiplied by width.
To calculate the area of a rectangle, all you need to do is multiply the base and the height. In this case 1 and 1.5. So the area is simply 1.5.
You use the surface area formula for a rectangle, but remember to leave out the top of it.
The perimeter is the sum of all four sides, so you need to calculate 2 x length + 2 x height. The fact that the rectangle is at the bottom of a triangle is irrelevant - except that in specific diagrams, information may be provided that lets you calculate the length or the width of the triangle.
A product is a binary operation which means that you need TWO numbers before you can calculate a product.
To calculate the area of a rectangle you need to multiply the width by the length
You CAN'T calculate the perimeter of a rectangle, knowing only its diagonal. You do need some additional information about the rectangle - such as its width, or its length, or perhaps the length/width ratio.
To find the perimeter of rectangle QRST, we need to determine the lengths of its sides. Given that line BC is 12√2, we can calculate the side lengths of the rectangle by rearranging the pieces. By analyzing the shapes and their relationships, we can determine the dimensions of QRST. Once we have the side lengths of the rectangle, we can calculate the perimeter by adding all four sides together.
Basically this isn't possible. Whenever you have an irregular curve, you need some kind of integration technique to get the area, or an estimate of the area. This can be quite simple, at least in principle: just approximate the area by narrow rectangles, calculate the area of each rectangle, and add everything up.
