Question

if the perimeter of rectangle is 36m.length is 3 more than twice of breadth then find its area​

Answer 1

Answer:

x=13. and y=5

Step-by-step explanation:

let x be the length and y be the breadth .

perimeter=2(x+y) ............1

2(x+y)= 36

Given:

the length is 3 more than twice the breadth

x=3+2y. .................2

solve 1 and 2

we get x=13 and y=5

Answer 2

Answer :-

• Area of Rectangle = 65 sq.m.

Explanation :-

Given :

• Perimeter of Rectangle = 36 m.

• Length of Rectangle is 3 more than twice of the Breadth.

To Find :

• Area of Rectangle.

Solution :

Let the Breadth be x.

Length of Rectangle will be 2x + 3.

We know that,

$\boxed{\checkmark}$ Perimeter = 2(l + b).

➙ 2(x + 2x + 3) = 36 m.

➙ 2(3x + 3) = 36 m.

➙ 6x + 6 = 36.

➙ 6x = 36 - 6.

➙ 6x = 30.

➙ x = 30 ÷ 6.

➙ x = 5.

Therefore,

• Length of Rectangle = 2x + 3 = 13 m.

• Breadth of Rectangle = 5 m.

Now, Let's Calculate Area.

We know that,

$\boxed{\checkmark}$ Area of Rectangle = l × b.

➙ Area = 13 × 5.

➙ Area of Rectangle = 65 cm²

Therefore, Area of Rectangle is 65 sq.m.
