The figure, not drawn to scale, consists of 1 Rectangle K and 1 Square L whose areas are in the ratio of 3 : 1. Given that
413 of Rectangle K is shaded, what fraction of Square L is shaded?
Area of Rectangle K |
Area of Square L |
3x13 = 39 u |
1x13 = 13 u |
Unshaded area |
Shaded area |

12 u |
Area of Rectangle K is the repeated identity.
Shaded area of Rectangle K is the same as the shaded area of Square L.
LCM of 3 and 13 = 39
Fraction of Square L that is shaded
=
1213 Answer(s):
1213
