Answer:
The area of the poster board is 432in²
Step-by-step explanation:
Area = base x height
Area = 18 x 24
Area = 432in²
Using the Pythagorean theorem:
Distance = √(13^2 - 12^2)
Distance = √(169 - 144)
Distance = √25
Distance = 5m
Bob age =x
Mary age= x+5
If we sum the ages
x+(x+5)=39
2x+5=39
then we clear x
2x=39-5
2x=34
x=34/2
x=17
Bob age =17
Mary age=17+5=22
