Answer 1

I hope this would help you

Answer 2

Answer:-

5 : 3 is length and breadth of Rectangle

₹ 7 per/m Rate of Fencing

Rs. 2800 is the Cost of Fencing

2800÷7

400 is the perimeter

5x is the length

3x is the breadth

=2(5x+3x)=400=2(5x+3x)=400

=10x+6x=400=10x+6x=400

=16x=400=16x=400

=x= 16400=x=16400

=x=25=x=25

(Eq) 1

=5×25=5×25

=125=125

(Eq) 2

=3×25=3×25

=75=75

125 unit is the length

75 unit is the breadth

(Area=L×B)

=125×75=125×75

=9375=9375

Therefore, 9375 is the area of plot
