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 )
A rectangle has perimeter 182 in. and length 52 in. What is the width?
The equation for the perimeter of a rectangle is 2x(a+b) where a is the length and b is the width. We can rewrite the question as the following: 2x(52+b) = 182 If both sides are divided by 2 we get: 52+b = 91 If we subtract 52 from both sides we get: 91 - 52 = 39. Thus the width of the rectangle is 39 in.
A rectangle with area the same as the perimeter?
The perimeter of a rectangle can be expressed as [2 * ( L+ W )]. The area of a rectangle can be expressed as [L * W]. Thus, the equation can be written as:2 * ( L + W ) = L * WThe answer originally posted on this page suggested the only solution is when the shape of the rectangle (four-sided object, opposite sides are equal length) is a square (four-sided object, all sides are equal length) with sides equal to 4.Actually, a 6 x 3 (or 3 x 6) rectangle satisfies the equation, as it has an area and perimeter both equal to 18.Keep in mind this is considering the rectangle sides must have integer values (positive number that is not a fraction), which is actually in accordance with the way the problem was posed going back to its original roots.
What is the equation of area of a diamond?
Same as a rectangle. It is, after all, a type of rectangle (lenght >< width)
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
