Marks: +1, -0

The diagonal of a quadrilateral shaped field is 24m and the perpendiculars dropped on it from the remaining opposite vertices are 8m and 13m. The area of the field is:

$252 m^2$
$1152 m^2$
$96 m^2$
$156 m^2$

Solution:

In ∆ADC
Area of ∆ ADC

=1/2×DP×AC

Area of ∆ADC

=1/2×8×24=96 m^2

Area of ∆BAC

=1/2×13×24=156 m^2

Area of Quadrilateral

=96+156=252 m^2
