Question

The length is 3 less than the twice of its width in a rectangle.

The perimeter of a rectangle is 100. Find length and width.​

Answer 1

According to the question,

length=2w-3

perimeter of rectangle=2(l+w)=100

2(2w-3+w)=100

3w-3=50

3w=53

w=53/3

Now, l=2w-3

So, l=(2*53/3) - 3

l=(106/3)-(9/3)

l=97/3

w=53/3

Answer 2

Answer:

hey dear ans..is here

Step-by-step explanation:

Let the breadth be b

Length is 2b - 16

Perimeter of the rectangle = 2( l + b) = 100 cm

=> 2 ( 2b - 16 + b) = 100

=> 3b - 16 = 100/2

=> 3b - 16 = 50

=> 3b = 66

=> b = 22 cm

length = 2 x 22 - 16 = 44 - 16 = 28 cm

Hence, length = 28 cm and breadth = 22 cm
