Solution
Dear student
Assuming the question as:
The perimeter of Pentagon and hexagon are 250 cm and 5018 m. Find the length of each side. Give formula of area of rectangle , perimeter of rectangle, area of square perimeter of square.
We
know
that
perimeter
of
pentagon
=
5
a
,
where
a
is
the
side
of
pentagon
.
Given
,
perimeter
of
pentagon
=
250
cm
⇒
5
a
=
250
⇒
a
=
250
5
=
50
So
,
a
=
50
cm
Also
,
perimeter
of
hexagon
=
6
b
,
where
b
is
the
side
of
hexagon
Given
,
perimeter
of
hexagon
=
5018
m
⇒
6
b
=
5018
⇒
b
=
5018
6
=
836
So
,
b
=
836
m
approx
.
Area
of
rectangle
=
l
×
b
,
where
l
is
the
length
of
rectangle
,
b
is
the
breadth
of
rectangle
.
Perimeter
of
rectangle
=
2
l
+
b
area
of
square
=
s
2
,
where
s
is
the
side
of
square
.
Perimeter
of
square
=
4
s
