Answer:
Area= 87.5
Perimeter= 39
Step-by-step explanation:
Area= l•w
Perimeter= sum of all sides
Since the average is <numbers combined> over <number of numbers>, we have 4+1=5 numbers (tests) and 92+91+94+79+x=356+x, resulting in
(356+x)/5=90. Multiplying both sides by 5, we get 356+x=450 and by subtracting 356 from both sides we get x=94 as the minimum score
