Formula = 2 (L + W)
Let x = width
x + 3 = length
Therefore
2( x + x + 3 ) = 90
2x + 3 = 45
2x = 42
x = 21
Please mark brainliest or thanks if it helped :D Therefore width=21 and length=24

length is x+3
breath is x
perimeter =2(l+b)
90=2×3+x+x
90/2 = 3+x+x
45= 3+x+x
45-3=2x
42=2x
42/2=x
21=x
breath is 21m
and length is 21+3=24m

21=x
breath is 21m
and length is 21+3=24m
