Question

If AB=14cm, BC=13cm, CD=17cm, DA=8cm and AC=15cm, then find the area of the quadrilateral ABCD.

Answer 1

Answer:

159cm sq.

Step-by-step explanation:

In triangle ABC

Height=13cm

Base=14cm

Area of triangle = 1/2×b×h

=1/2×14×13

=7×13

=91cm sq.

In Triangle ADC

Height=8cm

Base=17cm

Area of triangle =1/2×b×h

=1/2×17×8

=4×17

=68cm sq.

Therefore, total area of quadrilateral = 91+68cm sq.

= 159 cm sq.
