Answers
Width of TV screen = 24 Inch and TV will not fit into the cabinet
Step-by-step explanation:
Rithika buys an LED TV which has a 25 inches screen
TV screen size is always Diagonal
=> Diagonal = 25 inch
Height of TV screen is given = 7 inch
Let say Width of TV screen = W inch
Applying Pythagoras theorem
25² = 7² + W²
=> W² = 625 - 49
=> W² = 576
Taking square rooy both sides
=> W = 24
Width of TV screen = 24 Inch
But Rithika TV cabinet is 20 inches wide only
as 20 < 24
=> TV will not fit into the cabinet
