Answer:
The length is 7.50metres and the width is 5metres
Explanation:
Given the following
Length = 1.5Width
Perimeter = 25m
Required
Dimension of the room
Perimeter of the rectangular room = 2(L+W)
Since L = 1.5W
P = 2(1.5W+W)
P = 2(2.5W)
P = 5.0W
25 = 5W
W = 25/5
W = 5metres
Since L = 1.5W
L = 1.5*5
L = 7.5meters
The length is 7.50metres and the width is 5metres
M=30/22,5=1,33
m=25/x=1,33. ...>x=25/1,33=18,7
Since 1 < x < 5, adding each side by a, where a is negative, gives
a > ax > 5a
and adding b to each side gives
a + b > ax + b > 5a + b
or
5a + b < ax + b < a + b
Since 7 < f(x) < 23, it follows that
5a + b = 7
a + b = 23
Solve for a by eliminating b :
(5a + b) - (a + b) = 7 - 23
4a = -16
a = -4
Solve for b :
-4 + b = 23
b = 27
