Answer 1

${\fbox{\fbox{\huge\sf\purple{QuEsTiOn}}}}$

• find the cost of fencing a square patch of land side 20m at the rate of rs.37 per m

${\fbox{\fbox{\huge\sf\purple{AnSwER}}}}$

• The total cost of fencing is ₹2960.

$\bf{\red{To\:Find}}$

• Cost of fencing

$\bf{\red{Solution}}$

• Side of square = 20 m

$\large{ \blue{ \underline{ \underline{ \mathfrak{ \green{perimeter = 4 \times side}}}}}}$

$\bf{\red{According\:to\: question,}}$

$\large{ \tt : \implies \: \: \: \: perimeter = 4 \times 20}$

$\large{ \tt : \implies \: \: \: \: perimeter = 80 \: m}$

The perimeter of land is 80 m

Cost of fencing (per m) = ₹ 37

$\large{ \pink{ \underline{ \underline{ \mathfrak{ \blue{total \: cost \: = cost(per \: m) \times perimeter}}}}}}$

$\large { \tt : \implies \: \: \: \: \: total \: cost = ₹ 37\times 80}$

$\large { \tt : \implies \: \: \: \: \: total \: cost = ₹ 2960}$

The total cost of fencing is ₹2960.

$\small \bf \purple {ᴛᴏ \: ғɪɴᴅ}$

find the cost of fencing a spuare land

$\small \bf \pink {sᴏʟᴜᴛɪᴏɴ}$

the side of the square land= 20m

perimeter of the square land= 4 × side

$\sf = 4 \times 20m$

$\sf = 80m$

hence, the cost of fencing the patch of a land at the rate rs 37 per m

$\sf = 80 \times 37$

$\sf = 2960$
