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
Answer:
48 yr. old
Step-by-step explanation:
Assume daughter is 4 and mom is 10 times her age, so mom is 40.
10 (woman) * 4 (daughter's age) = 40 yr. old mom
Present day...
40 (yr old mom) + 8 (yrs later) = 48 yr. old mom today
4 (yr old daughter) + 8 (yrs later) = 12 yr. old daughter today
So, if mom is 4 times as her daughter's age today...
48 (yr. old mom) / 12 (yr. old daughter) = 4
