Answer:

For the value of x = 9, the perimeter of the shape will be 186 cm.

Step-by-step explanation:

Given

  • Length of rectangle = l = 5x+6 units
  • Breadth of rectangle = w = 4x+6 units

We know that Perimeter of rectangle = 2(L + w)  units

Given that the perimeter of shape 186 cm.

Thus, the equation becomes

2(L + w) = 186

2(5x+6 + 4x+6) = 186

2(9x+12) = 186

Divide both sides by 2

9x+12 = 93

9x = 93-12

9x = 81

Divide both sides by 9

x = 9

Thus, the value of x = 9

Hence, for the value of x = 9, the perimeter of the shape will be 186 cm.
