a rectangle plot of land is 50 m long. the cost of kevelling the plot at rs 12.59 per msquare is rs 20000. find the area of the plotand the breadth of the plot and the peremeter of the plot.
Answers
Answer:
Area of plot is 2000000 / 1259 m^2
breadth is 40000 / 1259 m
Perimeter of the plot is 205,900 / 1259 m
Step-by-step explanation:
Given,
Length of the plot : 50 m
Cost of leveling : Rs 20000
Rate of leveling : Rs 12.59 per m^2
=====================
We know,
Cost of leveling = Rate of leveling x area to be leveled
====================
Thus,
= > Rs 20000 = Rs 12.59 / m^2 x Area of plot
= > m^2 x Rs 20000 / Rs 12.59 = Area of plot
= > ( 2000000 / 1259 ) m^2 = Area of plot
==================
From the properties of rectangle,
Area of rectangle = Length x breadth
=================
= > ( 2000000 / 1259 ) m^2 = 50 m x breadth
= > { 2000000 / ( 1259 x 50 m ) } = breadth
= > 40000 / 1259 m = breadth
=================
From the properties of rectangle,
Perimeter of rectangle =2( length + breadth )
=================
Hence,
= > Perimeter of the plot = 2( 50m + 40000 / 1259 ) m
= > Perimeter of the plot = 205,900 / 1259 m
