The area of a quadrilateral ABCD is 325cm?
Find the length of the perpendicular drawn from
D on AC 25cm and the length of the
Perpendicular from B on AC is 14 cm
Answers
Answer :-
12 cm
Solution :-
Diagonal of the Quadrilateral ABCD ( d ) = AC = 25 cm
Length of the perpendicular drawn om AC from B ( h1 ) = 14 cm
Let the length of the perpendicular drawn on AC from D be h2
Area of the Quadrilateral ABCD = 325 cm²
Also, Area of the Quadrilateral = d/2 × (h1 + h2)
==> 325 = 25/2 × (14 + h2)
==> 325 × 2 = 25 × (14 + h2)
==> 650/25 = 14 + h2
==> 26 = 14 + h2
==> 26 - 14 = h2
==> 12 = h2
==> h2 = 12
Therefore the length of the perpendicular on AC from D is 12 cm.
QUESTION :-
The area of a quadrilateral ABCD is 325cm?
Find the length of the perpendicular drawn from
D on AC 25cm and the length of the
Perpendicular from B on AC is 14 cm .
SOLUTION :-
➠ diagonal of the quadrilateral ABCD is (d) = AC= 25cm.
➠ the length of the perpendicular drawn from
D on AC is ( h2)
➠ the length of the Perpendicular from B on AC is (h1) = 14cm.
➠ .°. Area of quadrilateral ABCD = d/2 × (h1 + h2)
➠ 325 = 25/2 × (14+ h2)
➠ 325 = 12.5 × ( 14 + h2)
➠ 325/12.5 = (14 + h2)
➠ 26 = 14 + h2
➠ h2 = 26 - 14
➠ .°. h2 = 12cm.
.°. the length of the perpendicular drawn from D on AC is 12cm.
