Question

The length of rectangle is twice its breadth if the perimeter is 90 meters find the length and breadth of the rectangle​

Answer 1

Answer:

Step-by-step explanation:

the length of a rectangle is twice its breadth

Let say breadth of rectangle = X  m

Then Length of rectangle = 2X  m

Perimeter of rectangle = 2( Length + Breadth)

= 2 ( 2X + X)

= 2 (3X)

= 6X  

6X = 90

=> X = 15

Breadth = 15 m

Length = 30 m

Answer 2

Answer:

length = 30, breadth = 15

Step-by-step explanation:

Let breadth be x

and, lenght be 2x

Perimeter of rectangle = 2(l + b)

90 = 2( 2x + x)

90 = 2 (3x)

90 = 6x

x = 90/6

x = 15

Breadth = x

= 15

Length = 2x

= 2 × 15

= 30m
