(a) 0.56 m²
(b) 0.60 m²
(c) 0.48 m2
(d) 0.64 m²
​

Answer 1

Answer:

0.64 m^2

Step-by-step explanation:

25cm = 25/100

0.25 m

16cm= 16/100

= 0.16

area of 1oane ( l.b) = 0.25 *0.16

= 0.0400 m^2

area of 16 panes = 0.0400*16

= 0 .64 m^2

Answer 2

Answer:

0.64 m

Step-by-step explanation:

25×16= 400

400×16= 0.64 m
