Question

what is the cost of cultivating a rectangular field 80m long and 35m wide at Rs15 per sq.m?​

Answer 1

Answer:

$= \geqslant length = 80m \\ breadth = 35m \\ area \: of \: the \: field = (l \times b)sq \: unit$

$\red{ = \geqslant (80 \times 35) {m}^{2} } =2800 \\ \pink{ = > rate \: of \: cultivation = rs15 \: per \: {m}^{2} }$

$\blue→•Cost \: of \: cultivation = \: rs \: (2800×15)$

=> Rs.42000

Perimeter of the field→[2×(length+breadth]units

=> [2×(80+35)]m

→(2×115)m

→230m
