Answer:
1. 30
2. 13 meters
Step-by-step explanation:
Let the number be x.
x - (10% of x) = 27.
x - 0.1x = 27
0.9x = 27.
x = 27/0.9
x = 30
The number is 30
Second question:
Length = 2x - 3
Width = x
Perimeter = 72
Perimeter = 2(l + w)
= 2(2x - 3 + x) = 72
4x - 6 + 2x = 72
6x = 72 + 6
6x = 78
w = 78/6 = 13
The width is 13 meters
