Answer:
2sqrt(10)
Step-by-step explanation:
Use the Pythagorean theorem.
x^2 + 3^2 = 7^2
x^2 + 9 = 49
x^2 = 40
x = sqrt(40)
x = 2sqrt(10)
Length =l
Height = h
Area function = l * h = 924
Perimeter function = 2i + 2h = 122
Divide by 2
I + h = 61.
Plug in I or h for the other variable
I * (61 - I) = 924
61i - i^2 = 924
Factor the function
(-I + 28)(I - 33) = 0
l = 33 as l cannot be negative
61 - 33 = 28
h = 28
Difference between h and l is 33-28=5
