с l2com 다. yon 4cm Rectangle a triangle. find the area of figure A ABCD is ABE is A B 600 sum 50m AD CBE. D C 6cm B. AR 4com BC =5cm​

Answer 1

area of rectangle ABCD = Length ×Breadth

=5×6 =30cm

area of triangle ABE =

$\sqrt{s(s - a) \: (s - b) \:( s - c)}$

where

$s = \frac{a + b + c}{2}$

$s = \frac{4 + 4 + 6}{2}$

$s = \frac{14}{2}$

s=7

=√7(7-4) (7-4) (7-6)

=√7×3×3×1

=√63

area of figure = 30 + √63
