Question

the length of a rectangle is 20 metre more than its width if the perimeter of the rectangle is 100 metre then find the length and breadth of rectangle​

Answer 1

Answer:

Breadth = 15 m

Length = 35 m.

Step-by-step explanation:

Length - 20 + Breadth

Perimeter - 2( l + b ) = 100

=> 2(20 + b ) = 100

So, Let the breadth be "X"

Then the length will be 20 + x

2 ( 20 + x ) = 100

So, then

2x = 30

X = 15

Therefore, The breadth of the rectangle is 15 m

So, therefore the length will be 20 + x

Means, 20 + 15

= 35 m.

Therefore,

Breadth = 15 m

Length = 35 m.
