Question

the area of rectangle is 18cm².its length is double than of its breath find its length and breadth
find its perimeter​

Answer 1

Answer:

length = 6 cm, breadth = 3 cm, perimeter 18 cm

Step-by-step explanation:

Let the breadth be x,

Then the length will be 2x

area of rectangle = length * breadth

using the formula:

• (2x * x) = 18
• 2x² = 18
• x² = 9
• x = √9
• x = 3

The breadth is 3 cm

Length:

• 2x
• 2(3)
• 6 cm

perimeter of rectangle:

• 2( length + breadth )
• 2( 3 + 6 )
• 2(9)
• 18 cm

Answer 2

Answer:

Step-by-step explanation:

Let the breadth = x cm

Length = 2x

2x *x = 18

     x² = 18/2

     x² =9

     x = √9

x = 3 cm

Breadth = 3 cm

Length = 2*3 = 6 cm

Perimeter = 2*(length + breadth)

 =2*(3+6)

= 2*9

Perimeter = 18 cm
