Perimeter of rectangle =40 cm (given)
condition :- length = 2× breadth +2
⇒l=2b+2
perimeter p=2(l+b)=40
⇒2(2b+2+b)=40
⇒2(3b+2)=40
⇒6b=40−4=36
∴b=6cm
l=2×6+2=12+2=14cm
∴ length =14 cm, breadth =6 cm
Hope this will help you..

Answer:
14 and 6
Step-by-step explanation:
perimeter = 2( length + breadth)
2(L+ B) = 40
given that , L = 2B +2
2(L + B) = 40
2(2B + 2 + B) = 40
B = 6
L = 2×6 + 2 = 14
