Step-by-step explanation:
length=x
breadth=3x/7
perimeter=2(x+3x/7)
2(7x+3x/7)
2(10x/7)
ans= 20x/7
Answer:
21m
Step-by-step explanation:
Given
breadth =3/7 of length
perimeter = 140 m
according to the question
2(length+breadth) = 140
2(L+3/7L) = 140
L+3/7L =70
10/7L=70
10L=7× 70
10L=490
L= 490 /10
L= 49
B = (3/7) L
B= (3/7)(49)
B= 3/7×49
B= 21m.
