Question

The length of a rectangle is 20m more than its width. If the perimeter of the rectangle is 100 m. then find the length and breadth of rectangle.
​

Answer 1

Answer:

so the length is 35 cm

Breadth is 15cm

Answer 2

Answer:

=> Length is 35m and Breadth is 15m

Step-by-step explanation:-

Given that:-

Length is 20m more than its width,

i,e., L = (20 + Breadth)

The perimeter of rectangle = $2 ( l + b) = 100m$

Assume that,

Breadth be 'x',

Then length be = $20 + x$

Therefore,

=> $2 ( 20 + x ) = 100$

=> $2x = 30$

=> $x = 15$... (Breadth)

Length $= 20 + x$

            $= 20 + 15$

            $= 35m$

Hence, the length and breadth of a rectangle are 35m and 15m respectively.
