Question

Oblicz Pole Powierzchni kwadratu o boku: a=8m a=0,5m a=2,5m a=4,5dm a=20km a=0,5dm

plissss.........

Answer 1

P=a*a

 

1) a= 8m

    P= 8*8=64m²

 

2) a= 0,5m=50cm

P= 50*50=2500cm²

 

3) a=2,5m

P=2,5*2,5=6,25m²

 

4) a=4,5dm

P=4,5*4,5=20,25dm²

 

5) a=20km

P=20*20=400km²

 

6) a=0,5dm=5cm

P=5*5=25cm²

Answer 2

P = a²

P = 8m x 8m

P = 64m

 

======================

 

P = a²

P = 0,5m x 0,5m

P = 2,5m

 

===========================

 

P = a²

P = 2,5m x 2,5m

P = 6,25m

 

============================

 

P = a²

P = 4,5dm x 4,5dm

P = 20,25dm

 

============================

 

P = a²

P = 20km x 20km

P = 400km

 

===============================

 

P = a²

P = 0,5dm x 0,5dm

P = 0,25dm
