The required perimeter of the rectangle is 12t + 4.
Given that,
The width of a rectangle measures (t-8) centimeters,
Its length measures (5t+6) centimeters.
The perimeter of the rectangle is to be determined.
The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
The perimeter of the rectangle = 2 length + 2* width
= 2 * (t -8) + 2 * (5t + 6)
= 2t - 16 + 10t + 12
= 12t - 4
Thus, The required perimeter of the rectangle is 12t + 4.
