Question

If the length of rectangle is double it its breadth and the perimeter is 40 M find the area ​

Answer 1

Answer:

800/9 m2

Step-by-step explanation:

Answer 2

length = 2 × breadth

perimeter = 40

we will first find out the length and breadth

perimeter = 2 ( length + breadth )

40 = 2 { 2(breadth) + breadth }

20 = 3(breadth)

breadth = 20/3

So, length = 2 × breadth

= 2 × (20/3)

= 40/3

Now, we will find the area of the rectangle

area = length × breadth

= (40/3) × (20/3)

= 800/6

= 133.33

hence, the area of the rectangle will be 133.33 m²
