Given,
The given two sides are 16cm and 22cm
And, Perimeter of Triangle is 64cm.
We know that,
Let the first side ( i.e. 16cm) be a
and the second side ( i.e. 22cm) be b
Putting the values,
64cm = 16cm + 22cm + c
c = 64 - 38
c = 26cm.
Semi-perimeter (s) = perimeter / 2
S = 64 / 2
s = 32
Now,
Using the Heron's Formula,
The given two sides are 16cm and 22cm
And, Perimeter of Triangle is 64cm.
We know that,
Let the first side ( i.e. 16cm) be a
and the second side ( i.e. 22cm) be b
Putting the values,
64cm = 16cm + 22cm + c
c = 64 - 38
c = 26cm.
Semi-perimeter (s) = perimeter / 2
S = 64 / 2
s = 32
Now,
Using the Heron's Formula,

Given : -
(a) = 16 cm
(b) = 22 cm
(c) = ?
We know that,
Therefore, third side of triangle (c) = 26 cm.
Now,
=
= (s) =
= (s) =
= (s) =
= (s) = 32
Now,
using Heron's Formula,
Area of triangle =
sq. unit
.
Area of triangle =
cm²
.
Area of triangle =
cm²
.
Area of triangle =
cm²
.
Area of triangle =
2×2×2×4cm²
.
Area of triangle =
32cm²
(a) = 16 cm
(b) = 22 cm
(c) = ?
We know that,
Therefore, third side of triangle (c) = 26 cm.
Now,
=
= (s) =
= (s) =
= (s) =
= (s) = 32
