Answer:
72.2 = 2x + 40.6
Step-by-step explanation:
Formula for perimeter of a rectangle = 2( width + lenght)
P = 2 ( w + l)
P= 2w + 2l   (i)
We have been given that width = x
and lenght = 20.3 inches and P = 72.2 inches
We substitute the values of P, w and l into equation (i)
72.2 = 2x + (2*20.3)
72.2 = 2x + 40.6
The equation to calculate the width of the frame is 72.2 = 40.6 + 2w and the width of the frame is 15.8 inches.
Data Given;
- Perimeter = 72.2 inches
- length = 20.3 inches
- width = x
Perimeter of a Rectangle
To solve this question, we have to apply a formula which is given as;
[tex]P = 2(L+W)\\[/tex]
substitute the values and solve for the width (w)
[tex]72.2 = 2(20.3+w)\\72.2 = 40.6 + 2w\\[/tex]
collect like terms
[tex]72.2-40.6 = 2w\\2w = 31.6\\2w/2 = 31.6/2\\w = 15.8[/tex]
From the calculations above, the equation that can be used to calculate the width of the frame is 72.2 = 40.6 + 2w and the width of the frame is 15.8 inches.
