Question

Find the area of a square plot of land whose each side measures 8 1/2​

Answer 1

Side = 81/2
= 40.5
Area of square = side * side
= 40.5* 40.5
= 1640.25

Answer 2

Square area FORMULA = S × S

Side = 8 1/2

$8 \frac{1}{2} = \frac{17}{2}$

$( \frac{17}{2} ) {}^{2} = \frac{289}{4}$

So 289/4 Is solution for that question☝️
