Question

Find area and perimeter of a rectangle whose length =3m and breadth =2•5m

Answer 1

ar =l x b
ar = 3 x 2.5
ar =7.5m =7.5x 100 =750cm
perimeter = 2( l+b)
= 2(3+2.5)
=6+5
= 11m =11x100=1100cm

Answer 2

Answer:

Step-by-step explanation:

Area of rec =l*b

Area =3*2.5

Area of rectangle =7.5msq

Perimeter =2 (l+b)

=2 (3+2.5)

2 (5.5)

=11 m
