Question

12. Perimeter of a rectangle is 18cm .If the sides are in the ratio 3:4. Draw the Rectangle.
​

Answer 1

Answer:

perimeter = 20

perimeter = 202(l +b) = 20

perimeter = 202(l +b) = 202(2k +3k) =20 [l:b = 2:3]

perimeter = 202(l +b) = 202(2k +3k) =20 [l:b = 2:3]5k=10

perimeter = 202(l +b) = 202(2k +3k) =20 [l:b = 2:3]5k=10k=2

perimeter = 202(l +b) = 202(2k +3k) =20 [l:b = 2:3]5k=10k=2so l=2k = 4

perimeter = 202(l +b) = 202(2k +3k) =20 [l:b = 2:3]5k=10k=2so l=2k = 4and b = 3k = 6.
