It is 2w.
SA= 2x(l+w)+2x(l+h)+2x(h+w) H= Height L= Length W= Width
w + 2x + 3w - 2xw = 2x + 4w - 2xw, in simplest form
2x + w = -w
A = LW; L : W = 2 : 1 means that L = 2x and W = x. So that,700 = (2x)(x)700 = 2x2350 = x2√350 = x18.71 = x = W37.42 = 2x = L
Surface area of a cuboid = 2*(l*w + w*h + h*l) where l = length, w= width and h = height So here surface = 2*(x*2x + 2x*h + h*x) = 2*(2x2 + 3hx)
P=126 L=9+2x w=x 126=2(9+2x)+2x 126= 18+4x+2x 126=18+8x 108=8x 13.5=x So W= 13.5m and L=36m
The phrase "varies directly as" means that there is a number k such that w = k(2x - 1). From the results given for w = 9 when x = 2, 9 = k(4 - 1), or k = 3. Then when w is 15, 15 = 3(2x - 1), or 15 = 6x - 3, or 6x = 15 + 3, or x = 18/6 = 3.
For simplicity, let's call the breadth 'L' and the height 'W'. The formula is A = LxW. We can use X to represent W (the height) and 2X to represent L (the breadth, which is doubled the height) and substitute into the formula: A = X times 2X. The area of the parallelogram mentioned would be 2X².

To multiply the expressions (8wx) and (3w), you multiply the coefficients and the variables separately. The coefficients (8) and (3) multiply to give (24), and combining the variables (wx) and (w) results in (w^2x). Therefore, the final result is (24w^2x).
