Answer 1

Answer:

B1 = 200/20

NOW,

A2 = 200*6//5=240sq cm

B2 = 10

l2 = 240/14

= 24

Perimeter of new rectangle = 2(l2+B2)

= 2(24+10)

= 2*34

= 68cm. ANS..

Answer 2

Answer:

b1 = 20020 = 10 cm

Now,A2 = 200×6/5= 240 sq cm

b2 = 10 cm

l2 = 24010 = 24 cm

Perimeter of new rectangle = 2(l2+b2)

= 2(24+10)= 2×34=68cm.
