Draw the quad... pqrs and draw diagnol with 10 cm so the triangle will be divided into 2 triangles by herons formula find the area of both triangles and add them to find th answer
samRyjel:
then how can I find the area of both of them..
By herons formula
But the lenght of SR=?
how I'm l supposed to find SR...??
s
(
s
−
a
)
(
s
−
b
)
(
s
−
c
)
,
A = \sqrt{s(s-a)(s-b)(s-c)},
where s is the semiperimeter of the triangle; that is,
s
=
a
+
b
+
c
2
.
s=\frac{a+b+c}{2}.
(
s

(
s
−
c
)
,
A = \sqrt{s(s-a)(s-b)(s-c)},
where s is the semiperimeter of the triangle; that is,
s
=
a
+
b

c
2
.
s=\frac{a+b+c}{2}.
Its given
