Question

if a perimeter of a rectangular is 130 meter if its length is five meter more than its breadth find the length and breadth of the field

Answer 1

Answer:

30

Step-by-step explanation:

Perimeter = 130

Let breadth be x

l = x + 5

$perimeter = 2(l + b)$

Substituting the values,

$2(x + y) = 130 \\ 2(x + (x + 5)) = 130 \\ 2(x + x + 5) = 130 \\ 2x + 5 = \frac{130}{2} \\ 2x + 5 = 65 \\ 2x = 65 - 5 \\ 2x = 60 \\ x = \frac{60}{2} = 30$
