Answer:
84.85cm
Step-by-step explanation:
Let the sides of the square be x
The perimeter of the square = 4x
Get x using the pythagoras theorem
x^2 + x^2 = 30^2
2x^2 = 900
x^2 = 450
x = 21.21cm
Perimeter of the plate = 4(21.21)
Perimeter of the plate = 84.85cm
If b is the base then the height h=b+6. As we have S=bh/2 then
36=b(b+6)/2;
b²+6b-72=0;
D/4=3²+72=81
b₁=-3-9=-12
b₂=-3+9=6.
The base is always positive so b=6, h=6+6=12.
Answer: base=6 ft, height=12 ft.
The total snowfall for listed 10 days is 349 cm.
Further explanation:
The sum of snow fell each day will give us the total snowfall for 10 days.
Given:
Snow fell on 10 days:
14 cm, 13 cm, 7 cm, 3 cm, 11 cm, 14 cm,
28 cm, 108 cm, 84 cm, 67 cm
So,

The total snowfall for listed 10 days is 349 cm.
