Question

Find the cost of ploughing at ₹10 per m of length 90 m and breadth50 m

Answer 1

Answer:

Given: Length of the rectangular field=110 m

Breadth of the rectangular field=85 m

Perimeter of the rectangular field=2(l+b)

=2(110+85)=2×195

Perimeter of the rectangular field=390 m

2

Cost to fence the field per metre=Rs.25

Cost to fence the field 390 metre=Rs.25×390=Rs.9,750‬

∴ Cost of fencing the field =Rs.9750

Answer 2

Given :-

→ Length of field = 90 m

→ Breadth of field = 50 m

→ Cost of ploughing per m² = Rs. 10

To Find :-

→ Cost of ploughing this field

Solution :-

→ As we're given that the we need to find the cost of ploughing . Here , we need to find the area of the field first .

$\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}$

$\star\: \boxed{\sf{\blue{Area\;of\;rectangle\;= Length \times Breadth }}}$

→ Let's find out by putting the values in the formula !

$\sf \implies 90\;m \times 50\; m$

$\sf \implies 4500\;m^{2}$

→ Now we need to find the cost ATQ  by using the unitary method

$\sf \implies 1\;m^{2} = Rs.10$

$\sf \rightarrow 4500\;m^{2} = 4500 \times 10 \\\\\\\ \rightarrow Rs. \; 45000$

∴ Cost of ploughing is Rs. 45,000

More to know :-

➝ Area of square = Side × Side

➝ Area of Rectangle = Length × Breadth

➝ Area of Triangle = 1/2 × Base × Height

➝ Area of Rhombus = 1/2 × Product of Diagonals

➝ Area of Circle = πr²
