One side of the rectangle is 10cm. and the second is 2 times larger. Its perimeter is 60cm. How long is the other side of the rectangle?
We express the sought-for unsettled length of the second side of the rectangle with the conditional variable “Y”
Taking into account the condition of such an example, we compose the following expression: (10 + Y) x 2 = 60.
The result of the calculation performed looks like this 10 + Y = 60/2 = 30 or Y = 30 – 10 = 20 centimeters.
Answer: 20 centimeters.
