The quadrilateral ABCD has area of 58 in2 and diagonal AC = 14.5 in. Find the length of diagonal BD if AC ⊥ BD.

Answer:

(look in the the Step by step)

Step-by-step explanation:

When the diagonals of a quadrilateral are perpendicular, the area of that quadrilateral is half the product of their lengths.

.. A = (1/2)*d₁*d₂

Substituting the given information, this becomes

.. 58 in² = (1/2)*(14.5 in)*d₂

.. 2*58/14.5 in = d₂ = 8 in

The length of diagonal BD is 8 in.

UNO [17]

$\qquad\qquad\huge\underline{{\sf Answer}}$

Both the given lines in graph intersect at point (5 , -2), the point must satisfy both the equations.

and if we check the options, we will observe that D. option has both the equations that satisfy the given conditions.

that is ~

$\qquad \sf \dashrightarrow \: x + y = 3$

put y = - 2,we will get :

$\qquad \sf \dashrightarrow \: x - 2 = 3$

$\qquad \sf \dashrightarrow \: x = 5$

so, 1st equation satifys the condition. let's check out 2nd one.

$\qquad \sf \dashrightarrow \: x + 2y = 1$

put y = -2

$\qquad \sf \dashrightarrow \: x + (2 \times - 2) = 1$

$\qquad \sf \dashrightarrow \: x - 4 = 1$

$\qquad \sf \dashrightarrow \: x = 5$

Hence, we can conclude that the Correct choice is D
