Question

ABCD is a quadrilateral with AB = 20 cm, BC = 15 cm,
CD = 25 cm, DA = 30 cm and LABC = 90°. The area of
the quadrilateral ABCD is​

Answer 1

Answer:

525 sq.cm

Explanation:

Given:-ABCD is a quadrilateral.

Proof:-area of ∆ABC=1/2×base×height

=1/2×20×15

=150sq.cm

area of ∆ADC=1/2×b×h

=1/2×25×30

=375sq.cm

total area of quadrilateral=sum of∆ABC+∆ADC

=150+375

=525sq.cm
