Question

1. multiply the perimeter of rectangle having the following dimensions.



a l=25.5 CM ;b=12.5 centimetre
b.l=12 CM;b=6CM
c.l=825CM;b=5 CM
d.l=3/4 Metre; b=1/2 Metre
e. l=75CM;b=420CM





answer step by step process​

Answer 1

Step-by-step explanation:

a. perimeter of rectangle=2(l+b)

=2(25.5cm+12.5cm)

=2×38

=76

b. perimeter of rectangle=2(l+b)

=2×(12cm+6cm)

=2×18

=36

c.perimeter of rectangle=2(l+b)

=2(825cm+5cm)

=2×830

=1660

d.perimeter of rectangle=2(l+b)

=2(0.75m+0.5cm)

=2×1.25

=2.5

e. perimeter of rectangle=2(l+b)

=2(75cm+420cm)

=2×495

=990
