Q9) 1-d

      2-c

      3-b

      4-a

Answer 2

Q1) Given-

Length-8cm

Breadth- 4cm

Perimeter of Rectangle = 2(l+b)

= 2(8+4)

=2×12

=24

Q2)

• 1-D

Perimeter = 2(l+b)

=2(10+14)

=2×24

=48

• 2-C

Perimeter of triangle = a+b+c

=3+4+9

=16

• 3-B

Perimeter = 2(l+b)=60

2(10+b)=60

10+b=30

b=30-10

=20

• 4-A

Perimeter=Side×4

Perimeter÷4=Side

=96÷4=Side

=24
