The are of a rectangle can be obtained by using the formula
A=L*W
Since we are already given with the L, which is (6x-2), and the width, which is (x-1), the area of the rectangle is then
A = (6x-2)(x-1)
which, upon further simplification will give us
A = 6x^2-2x-6x+2
Combining like terms will yield
A = 6x^2-8x+2
Hence, the area of the specified rectangle is represented by the expression 6x^2 -8x +2.
Step-by-step explanation:
Area of shaded region = area of exterior rectangle - area of interior rectangle
7 centimeters
First, you have to set up an equation using the formula for area of a rectangle:
L x W = H. Then, plug in what you know: 8 x W = 56. Then, solve for x by dividing 56 by 8: W=7.
Answer: a=0.58 ;b=0.42
