Question

1. Find the area, in hectare, of a field whose length is 240 m and perimeter is 700 m​

Answer 1

length of field=240m

perimeter=700m

perimeter of rectangle=2{L+B}

700=2{240+B}

700=480+2B

700-480=2B

2B=220

B=110=breadth

area of field=L*B

area=110*240

       =26400$m^{2}$

$1 m^{2} =0.0001 hectare$

26400*0.0001=2.64 hectares

hope it helped
