The length of a rectangle is twice it’s width. If the area of the rectangle is 162m ^2,find its perimeter
GalinKa [24]

Answer:

{ \tt{area = length \times width}} \\ { \tt{162 = 2w \times w}} \\ { \tt{162 = 2 {w}^{2} }} \\ { \tt{ {w}^{2}  = 81}} \\ { \tt{w = 9}}

  • width, w = 9 m
  • length, l = 2 × 9 = 18 m

{ \tt{perimeter = 2(l + w)}} \\ { \tt{p = 2(18 + 9)}} \\ { \tt{p = 2 \times 27}} \\  \\ { \underline{ \tt{ \:  \: perimeter = 54 \: m \:  \: }}}

American Gothic was painted in 1930 by Grant Wood. The length of a reproduction of the rectangular painting is 2 inches more tha
Veronika [31]

Answer:

Length: 11.95

Width: 9.95

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

To begin solving this question we need to create a formula to then solve. According to the information given in the question we can create 2 formulas.

P = 2L+2W

L = 2+W

<u>Where:</u>

  • P is the perimeter
  • L is the length
  • W is the width

Now we can replace L for the L in the P formula and solve for W, Like so....

43.8 = 2(2+W)+2W

43.8 = 4+2W+2W

39.8 = 4W

9.95 = W

Now that we have the value of W we can plug that into the L formula and find L

L = 2+9.95

L = 11.95

Finally, we can see that the value of the Length is 11.95 in and the Width is 9.95 in

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
