Answer 1

Answer:

l of rectangle =3x=3×10=30 units

b of rectangle=1x=1×10=10 units

Step-by-step explanation:

perimeter of sq.= 4×s

4×20

=80 units

perimeter of rectangle is= 2(l+b)

let ratio 3:1 be 3x,1x

2(3x+1x)

GIVEN: perimeter of sq. = perimeter of rectangle

2(3x+1x)= 4×20

2(4x)=80

8x=80

x=80/8

=10
