Question

Perimeter of rectangle is 186cm, if length is (5x+6) and breadth is (2x+66). Find the
value of x​

Answer 1

Step-by-step explanation:

2[5x+6+2x+66] = 186

7x + 72 = 93

7x = 21

x = 3

Given:-

• Perimeter of Rectangle = 186cm
• Length ,l = (5x + 6)
• Breadth ,b = (2x+66)

To Find:-

• The value of x

Solution:-

According to the Question

As we know that Perimeter of rectangle is calculated by

Perimeter of Rectangle = 2(l+b)

Where,

• l denote length
• b denote breadth

Substitute the value we get

:⟹ 2 { (5x + 6) + (2x+66)} = 186cm

:⟹ 2 { 5x +6 + 2x + 66} = 186

:⟹ 2 { 7x + 72) = 186

:⟹ 7x + 72 = 186/2

:⟹ 7x +72 = 93

:⟹ 7x = 93-72

:⟹ 7x = 21

:⟹ x = 21/7

:⟹ x = 3

Hence, the value of x is 3.
