Answer:
Then it is just a matter of plugging in the values into the formula. For example, if one base is 6 cm long, the other is 10 cm long and the height is 4 cm, the area is then (6 + 10) / 2 x 4 = 16 / 2 x 4 = 8 x 4 = 32 cm 2 (32 square centimeters).

Answer:
Katie won't have more than 100 seashells until the 6th day.
Step-by-step explanation:
No. of seashells to be collected = 100
Initial number of seashells in the collection = 34
No, of seashells found each day = 12
So, number of seashells collected in d days = 12·d
Total number of seashells collected after d days = 34 + 12·d
Number of days needed by Katie to save more than 100 seashells :
34 + 12·d > 100
Subtracting 34 from both the sides
⇒ 12·d > 66
⇒ d > 5.5
Hence, Katie won't have more than 100 seashells until the 6th day.
