• The length of a garden is twice its breadth

$\:\:$

• Breadth is 7.5 m

$\:\:$

• Cost of levelling the garden is 6 per sq. m

$\:\:$

• Let the length of garden be "x"

$\:\:$

Given that , the length of a garden is twice its breadth

$\:\:$

So,

$\:\:$

➜ x = 2(7.5)

$\:\:$

➨ x = 15 m

$\:\:$

• Hence length of garden is 15 m

➠ Length × Breadth

$\:\:$

$\underline{\bold{\texttt{Area of garden :}}}$

$\:\:$

• Length = 15m

• Breadth = 7.5 m

$\:\:$

➜ 15 × 7.5

$\:\:$

➨ 112.5 sq. m

$\:\:$

• Hence area of garden is 112.5 sq. m

$\:\:$

$\underline{\bold{\texttt{Cost of levelling :}}}$

$\:\:$

• Rate = Rs 6 per sq. m

$\:\:$

➜ 112.5 × 6

$\:\:$

➨ Rs 675

$\:\:$

• Hence cost of levelling the garden at Rs 6 per sq. m is Rs 675
