Answer 2

${\blue{\underline{\underline{\purple{\textsf{\textbf{Answer : }}}}}}}$

Dimensions of the rectangular park :

◩ length = 90 metres.

◩ breadth = 70 metres.

${\blue{\underline{\underline{\purple{\textsf{\textbf{Explanation : }}}}}}}$

Given that,

• The length and breadth of a rectangular park is in ratio 9 : 7.
• The total cost of fencing the park is ₹64,000 m² at the rate of ₹200/m²

Here,

• It is given the rate of fencing and the total amount spent on fencing is given.

So,

Perimeter of the rectangular park :

$\sf \longrightarrow \frac{Total \: amount \: spend \: on \: fencing}{Rate \: of \: fencing}$

Therefore,

Perimeter = $\sf \frac{64,0\cancel{00}}{2\cancel{00}}$

$\sf \to \: \frac{640}{2}$

$\sf \to \: 320m$

• Now we got perimeter as 320metres

❐ Further solving,

Assuming :

l (length) = 9x

b (breadth) = 7x

Again,

➪ $\sf \: 320 = 2(l + b)$

➪ $\sf \:320 = 2(9x + 7x)$

➪ $\sf \:320 = 2(16x)$

➪ $\sf \:320 = 32x$

➪ $\sf \:x = 10m$

Therefore dimensions are :

➡ length = 9x = 90metres.

➡ breadth = 7x = 70 metres.
