She decided to establish a square shaped school for rural people of perimeter 240 m. a) Find the dimensions of the plot. Also, calculate the side of the square plot for school. (Ans : L = 800 m, B = 400 m Side = 60 m)​

Answer 1

Answer:

see below

Step-by-step explanation:

given taht perimeter is 2400m. and as it is given that the plot's breadth is half of length so by this it is clear that it is a rectangular plot.

let length be x and breadth be x/2 and rectangle's perimeter formula is 2(l+b) so , ATQ. 2(x+x/2)=2400m

=> 2x+x=2400m

=> 3x=2400m

=> x= 2400/3=800metre

so breath is800/2=400.given perimeter of square is 240 so length will be 240÷4=60 m
