FILL IN THE BLANK QUESTION

3 mins • 1 pt

Oblicz obwód kwadratu, którego pole jest równe polu prostokąta o bokach 9 i 16.

Answer explanation

Pole kwadratu wynosi tyle samo, co pole prostokąta, czyli:

9 x 16 = 144

Bok kwadratu to pierwiastek kwadratowy ze 144, czyli 12 cm

Obwód kwadratu to 4 x 12 cm = 48 cm
