Answer 2

Answer:

Length of the rectangle=3m

1m=100cm

∴l=3×100cm=300cm

Breadth of the rectangle=75cm

(i) Perimeter of the rectangle =2(l+b)

=2(300+75)

=2×375=750cm

$\tt{ = \frac{750}{100} }$

=7.5m

(ii) Area of rectangle =l×b=300×75cm²

=22500cm²

$\tt{ \frac{22500}{100 \times 100} {m}^{2} = {2.25m}^{2} }$
