Question

The rectangle shown has a perimeter of 92 cm and the given area. Its length is 6 more than three times its width. Write and solve a system of equations to find the dimensions of the rectangle .

Answer 1

The answer is that the width is equal to 10 and the length is equal to 36.

Explanation:

Answer 2

Dimensions are 20cm & 26 cm .

Explanation:

Given that the rectangle shown has a perimeter of 92 cm and the given area. Its length is 6 more than three times its width. So let

• Lenght be x + 6
• Breadth be x.

======================================

Now According to Question ,

⇒ Perimeter = 2(l+b)

⇒ 92 cm = 2( x + x + 6 )

⇒ 92 cm = 2(2x + 6)

⇒ 92 cm = 4x + 12

⇒ 4x = ( 92 - 12) cm

⇒ 4x = 80cm

⇒ x = 80cm/4

⇒ x = 20 cm .

So , the lenght will be x + 6 = 26 cm and breadth will be x = 20 cm .

Hence the lenght of the rectangle is 26 cm and breadth is 20 cm .
