Step-by-step explanation:
the third side of triangle be x m.
Then, two equal sides of triangle =(3x-4)m
Given, perimeter of triangle =55m
∵
x
+
3
x
−
4
+
3
x
−
4
=
55
⇒
7
x
−
8
=
55
⇒
7
x
=
55
+
8
⇒
7
x
=
63
⇒
x
=
63
7
∴
x
=
9
Hence, the dimension of the triangle are 9m,
(
3
×
9
−
4
)
m and
(
3
×
9
−
4
)
m, i.e 9, (27-4), and (27-4)m, i.e. 9m, 23m, and 23m
