Answer 1

The perimeter of the television screen (in inches) is 129 inches.

Given that a television screen in the shape of a rectangle has a length of    40 inches and breadth $\frac{49}{2} inches$.

Perimeter of rectangle=2(length of rectangle+ bredth of rectangle)

Here the TV screen is the shape of rectangle

Therefore Perimeter of TV screen=perimeter of rectangle

Given the the length of TV screen=40 inches

The bredth of the TV screen= $\frac{49}{2} inches$.

Perimeter of TV screen=2(40 inches + $\frac{49}{2} inches$)

Perimeter of TV screen=(80+49) inches

Perimeter of TV screen= 129 inches

Therefore,The perimeter of the television screen (in inches) is 129 inches.
