Answer:
2.0 x 
Step-by-step explanation:
1. length = 3.2 x
m
width = 1.6 x
m
Area of a rectangle = length x width
= (3.2 x
) x (1.6 x
)
= 5.12 x

2. length = 1.28 x
m
width = 8 x
m
Area of a rectangle = length x width
= (1.28 x
) x (8 x
)
= 1.024 x

= 
= 20
= 2.0 x 
Thus,
The area of rectangle 2 is 2.0 x
times greater than the area of rectangle 1.
Answer:
7/20
Step-by-step explanation:
12/20+ -5/20
Answer:
Step-by-step explanation:
Let Naomi's wage = £ x
Reduction in wage = 10% of x = 0.1 *x = 0.1x
x - 0.1x = 252
0.9x = 252
x = 252/0.9

= £ 280
Weekly wage if she had received 10% pay increase
Increment = 10% of 280 = 0.1*280 = 28
Weekly wage after increment = 280 +28 = £ 308
