Which is the diameter of a rectangle whose circumference is 13653 cm and one side is 5431 cm​
leonid [27]

Answer:

See below

Step-by-step explanation:

If by circumference you meant perimeter and diameter you mean length, then here is my answer.

Perimeter = 2L+ 2W

13653= 2*L + 2*5431

13653= 2L + 10862     Subtract 10862 from both sides

2791= 2L Divide by 2

L= 1395.5

The diameter is 1395.5
