ok ok ok ok ok ok ok

Answer 2

Answer:

length is 23 m

Step-by-step explanation:

let the breadth be x and lenght 7 + x

perimeter = 2(L + B)

= 2( x + 7+ x)

= 2(2x +7)

but the perimeter is 78

so, 2(2x +7) = 78

2x + 7 = 78/2 = 39

2x = 39-7 = 32

x = 32/2

x = 16

so breadth is x = 16 m

and length is 7 + x = 7 +16 =23 m
