only to solved by Brainly moderators

Answer 1

let unknown value be 'x'

therefore,

86=2(25+x)

86/2=25+x

43=25+x

43-25=x

therefore,

x=18

Answer 2

Answer:let the breadth be 'b' meter

So ATQ

length is 25m and perimeter is 86m

Perimeter of rectangle = 2( l+b)

Using this

2(25+b)=86.............eq.1

25+b= 86/2

25 +b = 43

b= 43-25

b is 18m

So breath is 18meter.
