Question

the length and breadth of a rectangular field is in the ratio 3 upon 4 it its area is 6912 square cm what find its dimensions​

Answer 1

Answer:

Given, b:l = 3:4

=> l = 4k, b = 3k

Area = 6912

=> l*b = 6912

=> 3k(4k) = 6912

=> 12k² = 6912

=> k² = 6912/12 = 576

=> k = √576 = 24

So, length = 4k = 4(24)

Length = 96cm

Breadth = 3k = 3(24)

Breadth = 72cm
