Question

The sides ga D, 266m, 27m, 7 aretum respectively contained by sides is a rught angle. The angle the last Find it area two​

Answer 1

Answer:

The sides of a quadrilateral field taken order as

AB=26 m

BC=27 m

CD=7 m

and DA=24 m

Diagonal AC is joined

Now △ADC

AC

=AD

AC=

625

AC=25 m

Now area of △ABC

S=

=39 m

By using heron's formula

Area of △ABC=

S(S−AB)(S−BC)(S−CA)

=

39(39−26)(39−27)(39−25)

=

39×13×12×14

=

85179

=291.85 m

Now area of △ADC

S=

=28 m

By using heron's formula

Area of △ADC=

S(S−AD)(S−DC)(S−CA)

=

28(28−24)(28−7)(28−25)

=

28×4×21×3

=

7056

=84 m
