x2 = (x - 4)(x + 5)
x2 = x2 - 4x + 5x - 20
x = 20
The first room area = x2 = 202 = 400 ft2
The second room area = (x-4)(x+5) = 16 ft * 25 ft = 400 ft2

Can you make a rectangle out of two triangles and a square?
Sure, place a triangle's hypotenuse (longest side) on the other triangle's hypotenuse, that will give either a square or a rectangle. Then place the square on one end of the rectangle. For this to work though, the length of the square's side HAS to equal the length of the triangles hypotenuses, and likewise each triangle's hypotenuse much equal the length of a side of the square. Hope this is clear.
We are interested in the dimensions of a certain rectangle. This rectangle has length twice the side of the square and width three units less than its sides of this square. If the two areas are equal?
The rectangle is 12 units by 3 units.
What is the formula for the perimeter of a square and rectangle?
The perimeter of any rectangle is [ 2 x (length + width) ]. Since the length and width of a square are equal, the perimeter of a square is also [ 2 x (side + side) ] = (4 x side).
What parallelogram has all angles equal?
A rectangle has four angles of 90° each, also known as right angles. The special case is the square, which is a rectangle with four equal sides.
Which rectangle has the greatest area for a fixed perimeter?

A square is a flat plain figure whose four sides are of equal length.A rectangle is a flat plain figure whose lengths are longer that the widths.So a rectangle is not like a square!

Can a square be a rectangle but can a rectangle be a square?

Why is a square both a rectangle and a rhombus?
