Answer 2

Given :-

• Perimeter of a rectangular park = 156m
• Let the breadth of the park be x
• Therefore, length = 3x - 2

We know that :-

• Perimeter of a rectangle = 2 (l + b)
• L = length
• B = Breadth

According to the question:-

$= > 156m = 2(3x - 2 + x) \\ = > 156m = > 8x - 4 \: \: \: \: \: \: \: \: \: \\ = > 156m + 4 = 8x \: \: \: \: \: \: \: \: \: \: \: \: \\ = > 8x = 160m \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = > x = \frac{160}{8 } = 20 \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

Therefore,

• Breadth = x = 20m
• Length = 3x - 2 = 20 x 3 - 2 = 60 - 2 = 58m

Hope the answer helps you.
