Rectangle | Geometric Shapes | Maths


Rectangle (ചതുരം) is a  4-sided flat shape with opposite sides parallel and  equal .  All interior angles are right angles (90°).  

 Let length be 'l' and breadth be 'b'.
Area = l x b
Perimeter (ചുറ്റളവ്) = 2(l+b) 


Questions
1.ഒരു ചതുരത്തിന്റെ നീളവും വീതിയും കൂട്ടിയാൽ 10സെ.മീ.  കിട്ടുമെങ്കിൽ ചുറ്റളവ് എത്ര സെ.മീ.
(LGS Exserviceman-NCC 2018)
l+b=10 സെ.മീ
ചുറ്റളവ് = 2(l+b) = 2*10= 20 

2.40 മീറ്റർ നീളവും 30 മീറ്റർ വീതിയുമുള്ള ഒരു കുളത്തിന്റെ ചുറ്റളവ് എത്ര
(LGS Exserviceman-NCC 2018)
ചുറ്റളവ് = 2(l+b) = 2(40+30)= 140 മീറ്റർ
