Answer:
Step-by-step explanation:
SinCe it is given that perimeter of rectangle=perimeter of square
I.E.=2(l+b) = 4×S
since sides of rectangle are in ratio of 4:3
take length as 4x and breadth as 3 x
so according to condition
2(4x+3x)=4×21(sides of square is given 21m)
4x+3x=84/2=42
7x=42
x=42/7=6
x=6
so length of rectangle is 4x=4×6=24m
and breadth is 3x=3×6=18m
This is ur Answer☺☺
