Answer 2

Answer:

Answer:

Length and breadth of rectangle

will be 54 & 20 metres

respectively.

Step-by-step explanation:

According to the Question

It is given that,length of a rectangle is 6 m

less than 3 times its breadth .

The perimeter is 148 m

we have to calculate the length &

breadth of rectangle.

According to the Given Condition :

Let the length be y

and, breadth be x

Now, according to the given condition

length of a rectangle is 6 m less than 3

times its breadth .

3

> y = 3x-6 -----(i)

again,

Perimeter of Rectangle is given 148m

Perimeter of Rectangle = 2(length +

breadth)

148 = 2(length + breadth)

148/2 = (length + breadth)

74= x + y

--(ii)

Now, putting the value of y = 3x - 6 from

equation in equation (ii) we get

74= 3x -6 +x

80 = 4x

*→ x = 80/4

→ x = 20 m

Now, putting the value of x = 20 in

equation (1) we get

y = 3(20)-6

→ y = 60-6

> y = 54 m

Hence, the length and breadth of

the rectangle will be 54 & 20 m

respectively.
