Question

The length and treath strect-
are in the ratio of 13.7-it area
of rect is 22 75 cm Find the
ferimeter​

Answer 1

Step-by-step explanation:

Given, the length and breadth of a rectangle are in the ratio 3:2 respectively.

Then let the length and breadth of the rectangle be 3x,2x respectively.

If the sides of the rectangle are extended on each side by 1 m then length and breadth will be 3x+1 m and 2x+1 m.

According to the problem,

2x+1

3x+1

=

7

10

or, 20x+10=21x+7

or, x=3.

So length and breadth are 9,6 m respectively.

Now area of the rectangle be 9×6=54 m
