✧ \underline{ \underline{ \large{ \tt{ \: G \: I\:V \: E \: N}}}} :

  • Width of a rectangle ( w ) = 7t - 1.5 ft
  • Length of a rectangle ( l ) = 1.5t + 8 ft

✧ \underline{ \underline{ \large{ \tt{ \: T \: O\: F\: I \: N \: D}}}} :

❀ \boxed{ \large{ \text{Perimeter \: of \: a \: rectangle \:  =  \: 2(l + w)}}}

⟶ \large{ \tt{2(1.5 \: t \:  + 8 \: + 7t - 1.5}})

⟶ \large{ \tt{2(1.5t + 7t + 8 - 1.5)}}

⟶ \large{ \tt{2}(8.5t + 6.5)}

⟶ \large{ \tt{17t + 13}}

☄ \underline{ \boxed{ \boxed{ \tt{Our \: final \: answer : \underline{ \boxed{17t + 13 feet}}}}}}
