The required perimeter of the rectangle is designated by the conditional variable “Y”.
Given the information in this example, we form the following equation: Y = (180 / (90/10) + (90/10)) x 2.
The result of solving this equation will have the value Y = (180/9 + 9) x 2 = (20 + 9) x 2 = 29 x 2 = 58 decimeters.
Answer: The perimeter of the rectangle is 58 decimeters.
