Answer:
Let
L
=
the length of the rectangle and
W
=
the width.
If the length is four times the width, then
L
=
4
W
The formula for perimeter
P
is
L
+
L
+
W
+
W
=
P
or
2
L
+
2
W
=
P
Substituting
4
W
for
L
and
60
for
P
2
(
4
W
)
+
2
W
=
60
8
W
+
2
W
=
60
10
W
=
60
10
W
10
=
60
10
W
=
6

m
L
=
4
W
=
4
(
6
)
=
24

let length =2x
and breadth=x
perimeter of rectangle=2(l+b)
60=2(2x+x)
60/2=3x
30/3=x
10=x
l=2×10=20cm
b=10cm
