Question

The lenght and the breadth of a rectangle are in the ratio 4:3 if the breadth is 21 cm find the lenght

Answer 1

Answer:

length=4x

breadth=3x

also breadth=21cm

so, 3x=21

x=21/3

x=7

so length=4x=4*7=28cm

Answer 2

Answer:

28

ratio 4:3

breadth 21

when you multiple 7 x 3 we will get 21

so multiple 7 with 4 we will get 28
