Question

find the perimeter of a square field whose area is 49 hectare where one hectare equal to 10000 square

Answer 1

area of square =side^2
49=side^2
side =7 hectares
perimeter of square=4*side
=4*7= 28 hectares or 280000 m square

Answer 2

area of square=49hectare
we know that 1 hectare=10000
Area=49X 10000
Area=490000
area of square=Side^2
490000=side^2
(700)^2= Side^2
powers are cut
700=side
perimeter of square=4x side
perimeter=4X 700
peri=2800cm
