Question :- to find length of diagonal .
_____________________________________
Process :-
☆ 1 ) draw the rectangle of length = 20 m
and breadth = 15 m .
☆ 2 ) to find the length of diagonal of the rectangle , we can use Pythagoras theorem .
☆ Pythagoras theorem :- h² = b² + p² .
_____________________________________
Answer :-
☆ let diagonal of the rectangle be 'h' .
by using Pythagoras theorem ,
==> l = base = 20 m
==> p = height = 15 m
==> diagonal = h = ?
(hypotenuse)² = (base)² + ( height )²
diagonal = h² = (20)² + (15)²
= h² = (400 + 225 ) m²
= h² = 625 m²
= h = 25 m .
therefore, length of diagonal = 25 m .
