Heya☺

Let the length and breadth be 7x and 3x respectively

Perimeter of rectangle = 2(l+b)

30 = 2 ( 7x+ 3x)

30 = 20x

x = 3/2

Therefore

l = 7× 3/2 = 21/2
b = 3 × 3/2 = 9/2

Area of rectangle = l×b
= 21/2 × 9/2
= 189/4 unit^2
= 47.2 unit^2

✌✌ Hope this helps !

length=7x
Breadth=3x

P=2(l+b)
30=2(7x+3x)
30/2=7x+3x
15=10x
15/10=x
3/2=x

Length=7x=>7×3/2=>21/2m
Breadth=3x=>3×3/2=>9/2m

Area=l×b
=21/2×9/2
=189/4 or 47.2m²
