Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
While practising for his upcoming math exams, Hayes realised that the area of a circle he had just solved was equal to the perimeter of a square he had solved in the previous problem. If the area of the circle was 100, what's the length of one side of the square?

### Response:
 Hebu tuseme upande wa mraba ni s. Ili kupata umbo la mraba, unahitaji kuongeza pande zote, ambazo ni s+s+s+s = 100. Hivyo, 4s = 100. Hivyo, upande mmoja wa mraba ni s = 100/4 = 25.
