Question

Find the length of a rectangle whose breadth is 30cm and perimeter 200 cm​

Answer 1

Answer:

length of the rectangle = 70cm

Step-by-step explanation:

given , breadth of the rectangle = 30cm

also,    perimeter of the rectangle = 200cm

if we take 'l' as the length of the rectangle,

then the perimeter , p = 2(l + b)

=> 2(l+30) = 200 cm

=> 2l + 60 = 200 cm

=> 2l = 200 - 60 = 140 cm

=> l = 140/2

      = 70cm
