Question

The length of rectangle is 1cm its width and its perimeter is 14 cm . Then find the area of the rectangle​

Answer 1

Answer:

Step-by-step explanation:

The length of a rectangle is 1cm more than its width and its perimeter is 14cm,then what is the area of the rectangle?

Solution :)

Let we width of rectangle as x and length is 1 cm more than width than length = ( x + 1 ).

Perimeter of rectangle = 2(l+b)

Length = x + 1 = 4 cm

Width = x = 3 cm

Answer 2

Answer:

12 cm²

Step-by-step explanation:

Given:-

Length of the rectangle = x+1 cm

Breadth = x cm

Perimeter = 14cm

To find:-

The area of the rectangle.

Solution:-

Let breadth of the rectangle be= x

Perimeter of Rectangle = 2(l+b)

➜ 2(x+1+x) = 14

➜ 2(2x+1) = 14

➜ 2x+1 = 14/2

➜ 2x+1 = 7

➜ 2x = 7-1

➜ 2x = 6

➜ x= 6/2

➜ x = 3

Therefore, The breadth is 3cm.

Length= x+1

=> 3+1

=> 4cm

Area of rectangle= L × B

➜ 3cm × 4cm

➜ 12 cm

Therefore, The area of the rectangle is 12 cm².
