Question

the length of a diagonal of a square field is 220 m find the length of a side in metres and the area of the field in hectares​

Answer 1

Given area of square field =0.25 hectare
1 hectare =10,000m =0.25×10,000 =0.25×100 =2500 sq. m
Let side of square be 'a'
Area of square =a 2 a 2 =2500 ⇒a=50m
Diagonal of square = 2 a= 2 ×50=50 2 ​ m.

Answer 2

155.56m

0.242 hectares

Explanation:

`L=(220)/(√(2) ) =155.56m`

`A=(155.56^(2))/(10^(5) ) =0.242`
