Answer 1

$\huge{\bigstar{\mathfrak{\blue{\underline{\underline{Solution:}}}}}}$

$\bold{\underline{† Given:}}$

• Side of the garden = 9m
• Cost of fencing per metre = ₹10

$\bold{\underline{† To \: find:}}$

Length of the fence required and cost of fencing

$\bold{\underline{† Formula \: used:}}$

$\fbox {\sf{Perimeter of square = Side × 4}}$

$\bold{\underline{† Solved \: answer:}}$

⟹ Side of the square garden = 9m

⟹ Perimeter of the square garden

= 9×4

⟹ Length of fence required = 36m

Now,

⟹Cost of fencing per metre = ₹10

⟹Cost of fencing 36m = 36×10

⟹Total cost of fencing the garden

= ₹360

$\bold{\underline{† Final \: answers:}}$

• Length of the fence = 36m
• Total cost of fencing = ₹360
