156 It is impossible to calculate the area of a rectangle from its perimeter if no other dimension is known. The area of a rectangle is the product of its length and width, and the perimeter is twice the sum of its length and width.
rectangle with 10" length and 2x-4 width 60" area
There is no way to compute the dimension of a rectangle from its area. 40 square inches, you see, could be 1"x40" or 2"x20", or 4"x10", or . . . . . . but they would all be 40 square inches.

When linear dimensions are increased by a factor of 'N', area increasesby the factor of N2 and volume increases by the factor of N3.(1.10)3 = 1.331 = 33.1% increase
-- If they give you the length and the area, then you don't have to look very hard to find the area. It's right there in front of you, and you only need to copy it. -- If they give you the area and one dimension, then the quotient of (area) divided by (the given dimension) is the missing dimension.
I assume lbh in the question means length, base (or width) and height. Those three dimensions multiplied together calculate the volume, not the area, of the figure for cubic dimension. The area is calculated by multiplying the length and the width for squared dimension. In simpler terms; Area of rectangle is lw; Volume is lwh.
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.
