Question

the ratio of the length and the breadth of a rectangle is 7:5 find the following (a) if the breadth is 14 then find the length of the rectangle. (b) if the length is 84 m then find the breadth of the rectangle.​

Answer 1

Answer:

• If the breadth is 14 cm then the length of the rectangle is 19.6 cm.
• If the length is 84 m then the breadth of the rectangle is 60m.

Step-by-step explanation:

If the common multiple is x and the ratio of the length and the breadth of a rectangle is 7:5

Then the length of the rectangle = 7x

and breadth of rectangle = 5x

a)  If the breadth is 14 then find the length of the rectangle.

Breadth = 14 cm

5x = 14

x = 14/5

x = 2.8

So, length of rectangle = 7(2.8)  = 19.6 cm

b) If the length is 84 m then find the breadth of the rectangle.

7x = 84

x = 84/7

x = 12

So, breadth of the rectangle = 5(12) = 60 m.
