Question

A farmer puts a rope 30m round a rectangular garden whose length is 10m. What is the breadth of the garden

Answer 1

GIVEN:

• A farmer puts a rope 30m round a rectangular garden
• Length of the rectangular garden = 10 m

TO FIND:

• What is the breadth of the rectangular garden ?

SOLUTION:

Let the breadth of the rectangular garden be 'b' m

We have given that, a rope 30m round a rectangular garden.

It means that, the perimeter of the rectangular garden is 30 m

We know that the formula for finding the perimeter of rectangle is:-

$\large{\boxed{\bf{\star \: PERIMETER = 2(L+B) \: \star}}}$

According to question:-

On putting the given values in the formula, we get

• Perimeter = 30 m
• Length = 10 m
• Breadth = b m

$\rm{\hookrightarrow 30 = 10 + b}$

$\rm{\hookrightarrow 30-10 = b }$

$\bf{\hookrightarrow 20 \: m = b }$

❝ Hence, the Breadth of the rectangular garden is 20 m ❞
