perimeter of rectangular grassy plot=2(length+breadth)
189=2(l+10.5)
189=2×l+21
189-21=2×l
168/2=l
84=length
Area=length×breadth=84×10.5=882 m²
189=2(l+10.5)
189=2×l+21
189-21=2×l
168/2=l
84=length
Area=length×breadth=84×10.5=882 m²

perimeter = 2( L+ B )
189 = 2( L + 10.5)
⇒2L= 189 - 21
=168
⇒L =84 m
now area = L× B
= 84× 10.5
=882
Area = 882 m²
189 = 2( L + 10.5)
⇒2L= 189 - 21
=168
⇒L =84 m
now area = L× B
= 84× 10.5
=882
Area = 882 m²
