Question

I can't solve it..
Can someone????

Answer 1

Total area covered can be us 18×20=360 cm^2

But we r required to cover 324cm^2

Let the new breadth be x and length remains same

Thus 18 ×x = 324

X= 18

Thus new breadth should be 18 cm

Original was 20

Decreased 2 cm

Thus the breadth should be decreased by 2 cm

Hope it is helpful tanisha

Answer 2

Answer:

1.8cm

Given area is 324

And length 20

Length x breadth =area

20x new breadth =324

New breadth =16.2

Reduction needed =18-16.2=1.8cm
