Answer:
The price of the item would be $45.90
Step-by-step explanation:
The new price is 45.90
The original price is 51
Find the discount of 10 %
51*10%
51*.10
5.1
Subtract this from the original price
51- 5.1
45.9
first and second choice
238 cm
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
