What is the area of a rectangle with a perimeter of 30cm?
Let h and w equal the dimensions of the rectangle and A equal its area 2h + 2w = 30 The perimeter of the rectangle is the sum of its sides, two widths and two heights h*w = A The formula for the area of a rectangle We have two equations but three unknown variables. Without more information about this rectangle, it is impossible to solve for the area from the perimeter alone unless this rectangle was specified as being a square (which gives us a third equation, b = h )
Suppose rectangle E has an area of 9 square centimeters and rectangle F had an area of 900 square centimeters The two rectangles are similar What is the scale factor from rectangle E to rectangle F?
100 is the scale factor
How is the area triangle related to the area of a rectangle?
two right triangles = full rectangle That is - if you multiply height times base of a triangle, the area will be 1/2 of a rectangle having the same height, and a width the same as the triangle base.
How do you find the area of a rectangle two ways?
multiply the base by the height
How do you calculate the area of one arrow sign?
To find the area of an arrow you can first divide it into two shapes, a rectangle and triangle. First find the area of the rectangle then the area of the triangle. Then when you find both areas of the two shapes add them up to get the area of the arrow. If you don't know how to find the area of those two shapes you are so far lost.
What two dimensions are multiplied when finding the area of a rectangle?
the two dimensions that are multiplied are the top long layer and one of the sides to figure out your area of your rectangle and square
What is the formula of finding an area?
in finding the area if a square or rectangle multiply the length and width, for a triangle, multiply length and width divided by two.
What is the surface area for a rectangle that is 50 in?
You need two dimensions to calculate the area of a rectangle. Area = length multiplied by width.
Area to get the surface area of a rectangle?
Multiply the length by the width. If the rectangle is a square the two dimensions will be the same
Formula for finding area of rectangle with two inscribed circles?
Assume that the two inscribed circles are "side-by-side" and have the same radii of r, then: A= 8 x r x r.
What are the two steps in finding the area of a square?
To find the area of a square you multiply the length by the width. Since it is a square and not a rectangle you will be multiplying the same number because all the sides are the same length.
How can knowing the formula for the area of a rectangle help you find the surface area of a prism?
The cross-section of a prism is the same - it is the same as the shape of the two parallel "bases"; this cross-section can be any shape, not necessarily a rectangle. Each side of a prism is rectangular, so knowing the formula for a rectangle will help you along to finding the surface area of the prism by helping you to calculate the area of the sides; however, you will still need to be able to calculate the area of the bases (unless it is given to you), for which knowing the area of a rectangle may not (usually will not) help.
How is finding the area of a parallelogram like finding the area of a rectangle the same?
The formula for either polygon is multiply any base by the height of the figure perpendicular to that base; furthermore, you can see the similarity by making dotted lines inside the parallelogram so that it forms two triangles on the sides and a rectangle the middle. Now you could find the areas of the triangles and the rectangle and add them to find it is the same as if you take the base times the height or you can move one triangle to the other side next to the second triangle and you will see that it makes the parallelogram into a rectangle which is why finding the area is the same formula. Also, imagine taking a rectangle and pushing two bases together without breaking the figure. You will have changed the angles but all the sides will have stayed the same. Now just think has the amount of space inside the figure changed, no.
What are the steps to solving the area of a two dimensional shape?
If a regular 2D shape - a square or rectangle - times the length by the width to get the area.If the shape is irregular than drawing squares inside the shape will aid in finding the total area. There are other ways worth studying.The area of a right-angle triangle is half the size of a rectangle or square. The triangle's base x side will give the area of the rectangle or square. Dividing by 2 will halve the rectangle or square, so giving the area of the right-angle triangle.
How would you find the area of a rectangle if the rectangle was 20cm -9cm?
29
What is the area of a rectangle with a perimeter of 30cm?
Let h and w equal the dimensions of the rectangle and A equal its area 2h + 2w = 30 The perimeter of the rectangle is the sum of its sides, two widths and two heights h*w = A The formula for the area of a rectangle We have two equations but three unknown variables. Without more information about this rectangle, it is impossible to solve for the area from the perimeter alone unless this rectangle was specified as being a square (which gives us a third equation, b = h )
How you can use a generic rectangle to multiply two numbers.?
If the length and the breadth of the rectangle represent the two numbers, then the area of the rectangle is equal to their product. But, how do find the area? You multiply the two numbers. So this appears to be a long way to do something that is inherently straightforward!
