Sagot :
Step-by-step explanation:
Width
= 10 meters
Length
= 15 meters
Explanation:
Given:
Width
=
x
Length
=
2
x
−
5
Perimeter
=
50
Perimeter
=
2
×
length
+
2
×
width
Substitute:
50
=
2
(
2
x
−
5
)
+
2
(
x
)
Simplify:
50
=
4
x
−
10
+
2
x
50
=
6
x
−
10
60
=
6
x
x
=
10
Substitute (FINALLY)
Width:
x
=
10
So width
= 10 meters
Length:
2
x
−
5
=
2
(
10
)
−
5
=
20
−
5
=
15
So length
= 15 meters
