Answer 1

Answer:

Step-by-step explanation:

Perimeter of Rectangle=2(L+B)

=2(250mm+1.5m)

=250mm=(250/10)cm

=25cm

=1.5m(1.5*100) cm

=150cm

=2(25+150)cm

=2*175cm

=350 cm

Correct answer is 350 cm.

12 x 4 = 48 ( 4sides)

corect answer = 48

Answer 2

Answer:

350 cm

Step-by-step explanation:

Given sides of rectangle are

length = 250 mm = 25 cm

breadth = 1.5 m = 1.5×100=150cm

now Perimeter = 2[length+ breadth]

P=2[l+b]=2[25+150]=175×2

[P= 350 cm]

∴ perimeter of rectangle is 350 cm.
