Question

the length and breadth of a rectangle are in ratio 9:7 find the perimeter of the rectangle if the breadth is 378cm

Answer 1

Answer:

Let the length be 9x

breadth be 7x

According to the question:-

7x = 378cm

x = 378÷7

x = 54cm

So,

length = 9x = 9×54

x = 486cm

Then the perimeter = 2(l+b)

=2(486+378)

=2 × 864

=1728cm
