Question

A rectangular plot is as half as long as it is broad.the area of the plot is 2/3 hectare. The length of the plot is?​

Answer 1

Answer:

Length=200/square root(3) m

Step-by-step explanation:

Given b=l/2.

Also area=2/3 hectare.-----(1)

1 hectare =10000m^2.

Area of rectangle=l*b

=l*(l/2)

=l^2/2-----(2)

Now equating (1)&(2),

l^2/2=(2/3)*10000

l^2=40000/3.

Taking square root on both sides,

=>l=200/square root(3)m.
