Question 27

$12m^2$ is the area of

(a) a square with side 12 m
(b) 12 squares with side 1 m each
(c) 3 squares with side 4 m each
(d) 4 squares with side 3 m each

Answer 1

For option (a), Area of a square with side $12m=12\times 12=144m^2$
$[\because areaofsquare=(side{)}^2]$
For option (b), Area of 12 squares with side 1 m each $=12\times 1\times 1=12m^2$
For option (c), Area of 3 squares with side 4m each $=3\times$ Area of square of side 4 m
$=3\times 4\times 4=48m^2$
For option (d), Area of 4 squares with side $3m=4\times$ Area of square of side 3 m
$=4\times 3\times 3=36m^2$
Hence, option (b) is correct.
