The area of a square field is $$80\dfrac {244}{729}$$ square metres. Find the length of each sides field.
Correct option is C. $$8\dfrac {26}{27}m$$
Given area of square field $$= 80 \dfrac{244}{729} m^2$$Let us assume that side of square field is x
Then area of field $$= x^2$$
According to question
$$x^2 = 80 \dfrac{244}{729} m^2$$
$$x^2 = \dfrac{58,564}{729} m^2$$
$$x = \dfrac{\sqrt{58,564}}{\sqrt{729}} m$$
$$x = \dfrac{242}{27} m$$
Hence side of field is $$8 \dfrac{26}{27} m$$.
Option (C)
