Question

The ratio of the length and of a rectangle is 7:5 . Find the following I) If the breadth is 40m then find the length ii) If the length is 84m.Find the breadth. ​

Answer 1

Answer:

Step-by-step explanation:

Length =7:5

Let  length and width is  7x m and 5x m respectively

Width =40m

5x=40

or,x=40/5

x= 8

​ ∴length=7x=7×8=56m

then length is 84m

7x=84

or x=12

5x=5×12=60 m
