Answer:The perimeter of the rectangle is
or 15.66 inch.
Explanation:
Length of strip (I) = ![2\frac{1}{2} inch=\frac{5}{2}inch](https://tex.z-dn.net/?f=2%5Cfrac%7B1%7D%7B2%7D%20inch%3D%5Cfrac%7B5%7D%7B2%7Dinch)
Length of strip (II) = ![5\frac{1}{3} inch=\frac{16}{3} inch](https://tex.z-dn.net/?f=5%5Cfrac%7B1%7D%7B3%7D%20inch%3D%5Cfrac%7B16%7D%7B3%7D%20inch)
According to question two strips of length
and two strips of lenght
is used in making rectangle:
Perimeter of rectangle = Sum of all sides of rectangle
Perimeter of rectangle =![\frac{5}{2} inch+\frac{5}{2} inch +\frac{16}{3} inch+\frac{16}{3} inch=\frac{47}{3} inch](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B2%7D%20inch%2B%5Cfrac%7B5%7D%7B2%7D%20inch%20%2B%5Cfrac%7B16%7D%7B3%7D%20inch%2B%5Cfrac%7B16%7D%7B3%7D%20inch%3D%5Cfrac%7B47%7D%7B3%7D%20inch)
The perimeter of the rectangle is
or 15.66 inch.
