Answer:
the answer will be
breadth=16metres
length=21 metres
Step-by-step explanation:
let breadth be x so,length will be 5+x metre. it is given that perimeter is 74metres. so 2(5+x+x)=74. 2x+5=37 so x= 37-5/2 so x will be 16 hence solved

Answer:
Length = 21 m.
Bredth = 14 m.
Step-by-step explanation:
Given :-
- Breadth of the rectangular field = x
- length of the rectangular field = x+5
[As it is given here that the length is 5 more the breadth]
{ To find, the dimensions of the field when its perimeter is 74 m}
we got an equation -
2(x + x+5) = 74
Solution :-
⇒ 2(x + 5 + x) = 74
⇒ 2(2x + 5) = 74
⇒ 4x + 10 = 74
⇒ 4x = 64
⇒ x = 16
_______________________________
We got breadth, 16 m
and length ( x+5), 21m
