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.
