Answer:
$356
Step-by-step explanation:
To solve this problem, use this: (200 * 3.78) - (200 * 2)
(200 * 3.78) - (200 * 2)
<em>200 * 3.78 is the same as 2 * 378, which is 756.</em>
756 - (200 * 2)
<em>200 * 2 is the same as 4 * 100, which is 400.</em>
756 - 400
<em>Subtract 400 from 756 to get 356.</em>

The percentage change in perimeter is 100%.
The percentage change in area is 300%
<h3>How to find perimeter and area?</h3>
The perimeter of the sandbox = 2l + 2w
where
Therefore,
perimeter = 2(10) + 2(6)
perimeter = 20 + 12 = 32 ft
The area of the sand box = lw
area = 10 × 6 = 60 ft²
If the length and width are doubled,
length = 2(10) = 20 ft
width = 2(6) = 12 ft
hence,
perimeter = 2(20) + 2(12) = 40 + 24 = 64 ft
area = 12 × 20 = 240 ft²
Therefore,
percentage change in perimeter = 64 - 32 / 32 × 100 = 100%
percentage change in area = 240 - 60 / 60 × 100 = 18000 / 60 = 300%
