Question

The perimeter of a rectangular plot of land is 80 m and its breadth is 16 m. Find the length and area of the plot.

Answer 1

As, a perimeter 80m

⇒` 2"(Length+Breath)"=80` 

⇒` 2"(Length+16)"=80`  

⇒`2xx"Length"+32=80` 

⇒`2xx"Length"=80-32` 

⇒`"Length"=48/2` 

∴ `"Length"=24m` 

Now, the area of the plot =`"length" xx "breadth" ` 

=`24xx16` 

=`384m^2` 

So, the length of the plot is 24 m and its area is `384. m^2`
