Given,
A = L x W
L = 3x + 5
W = x - 2
Therefore,
A =[tex](3x + 5)(x - 2)[/tex]
A = [tex]3x(x - 2) + 5(x - 2)[/tex]
A = 3[tex]x^2 - 6x + 5x - 10[/tex]
A = [tex]3x^2 - x - 10[/tex].
Multiply the duration of the bottom, b, by the height, h, to locate the overall area. The equation for the place, A, of a rectangular or rectangle region may be written as: A = b * h. In our instance, the base, b, is 12 inches, and the peak, h, is five inches. consequently, the location is 12 inches increased by 5 inches or 60 square inches.
the perimeter P of a rectangle is given by the system, P=2l+2w, wherein l is the length and w is the width of the rectangle. The area A of a rectangle is given by way of the formulation, A=lw, where l is the duration and w is the width.
