A = LW divide by W to both sides A/W = L
would think you say 6ft*8ft = 48ft^2formel:If a rectangle has length l and width wit has area A = lw,
The base of a prism is always rectangular, so the area, A, =lw. l is length, w is width, of the base.
The area of any rectangle is simply the product of the length and width '' LW=A'' where L=length, W=width and A=area. So the answer is 11.24 X 61.8 = 694.632
The area of a rectangle is calculated by the formula: A = lw (area = length times width). If you know any two of those values, you can insert those values in the formula and calculate the third one.
Suppose that the area of the rectangular base is: lw then if the height is: h the surface area is: lw + lh + wh I believe that formula is for the surface area of a rectangular prism...
What is the area of a 50x15 rectangle? A = lw = 50x15 = 750
A = 224 ft^2 A = lw substitute the given value for A: 224 = lw In order to find the possible values for l and w, you should find all the factors of 224. Factors of 224 are 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 112, and 224. Thus, all possible solutions for l,w are 1, 224; 2,112; 4, 56; 7, 32; 8, 28; and 14, 16.
Re-arrange this equation: L=length W=width H=height S=surface area S = 2(LW+HW+HL) S/2 = LW+HW+HL (S/2) - LW = HW+HL (S/2) - LW = H(W+L) ((S/2) - LW)/(W+l) = H

The formula for the area rectangle
A =Lw....A- areal - lengthw - width
2(LW)+ 2(LW)+ 2(LW) 2 times lenghth times with, plus 2 times lenghth times height, plus 2 times with times height
To find the total surface area of a prism you add the lateral area and the areas of the two congruent bases. The formula is:Surface area = L.A. + 2B, where B is the area of the base.S.A. = L.A. + 2BSince the L.A. = 2(lh + hw) added to the area of the two bases, 2B = 2lw, another formula for the surface area can be S.A. =2(lh + hw + lw).By substituting the given values, l = 6 in, h = 2 in, and w = 8 in, in the surface area formula we have:S.A. = 2(lh + hw + lw)S.A. = 2[(6)(2) + (2)(8) + (6)(8)] = 2(12 + 16 + 48) = 2(76)S.A. = 152Thus, the surface area of the prism is 152 square inches.
Surface Area= 2(lw+lh+wh) Volume= lwh
