Answer:

10 is this right answer i don t no but is this is wrong answer please forgive me please

Answer 2

Answer:

let catch the solution...

now we found the dimensions

B= 8 mtr.

L= 12 mtr.

Step-by-step explanation:

let us consider the rectangular

breadth (B) = b

length (L) = b+4

perimeter is 40 (given)

now,

2( b+b+4 ) = 40

2( 2b+4 ) = 40

4( b+2 ) = 40

b + 2 = 40/4 →10

b+2 = 10

b= 8

we found the breadth B = 8 m

now, we can get the length

L = b+4

L = 8 + 4

L = 12 m
