1. Multiple Choice Questions (MCQ) Choose the correct option.
(1) The sides of a rectangle are 250 mm and 1.5 m. The perimeter in cm is
(b) 350
(c) 250
(d) 550
(ii) If the side of a square is 12 cm, its perimeter in
(a) 450​

Answer 1

Step-by-step explanation:

● length=1.5 m=150 cm

breadth=250 mm=25 cm

Perimeter = 2(length+breadth)

= 2(150 cm + 25 cm)

= 2 X 175 cm

= 350 cm

●Each side of square=12 cm

Perimeter=4 X a (side)

=4 X 12 cm

=48 cm

Answer 2

Answer:

1. Length =1.5m =150 m

breadth=250mm=25cm

Perimeter=2( Length+Breadth)

= 2(150cm+25cm)

= 2×175cm

=350cm

2.) Each side of square=12cm

perimeter= 4×a (side)

=4× 12cm

= 48cm
