Question

the perimeter of a rectangle is 80 metres and its length is one metre more than twice the breath. what are its length and breadth ​

Answer 1

let breadth =x

then length = 2x+1

2(2x+1+x)=80

80=2(3x+1)

80=6x + 2

6x=78

x=13

breadth =13m

length=27m

Answer 2

Step-By-Step Explanation

$the \: perimetre \: of \: the \: rectangle = 80m \\ the \: length \: of \: the \: rectangle = 2x + 1 \\ 80 = 2(2x + 1 + x) \\ \frac{80}{2} = 3x + 1 \\ 40 = 3x + 1 \\ 4 - 1 = 3x \\ 39 = 3x \\ \frac{39}{3} = x \\ 13 = x \\ \\ breadth \: of \: the \: rectangle = 13m \\ length \: of \: the \: rectangle = 2 \times (13) + 1 \\ = 27$Hope It Helps You♥️
