We can add the money he spent to the money he had left to find the total.
4.85 + 15.9 + 8.20 = 28.95
He started with 28.95
Answer:
Area = 40mm
Example:
The below-solved example problem may be useful to understand how the values are being used in the mathematical formulas to find the trapezoid area.
Example Problem :
Find the area of a trapezoid having the bottom length a = 15 cm, top length b = 12 & height h = 9 cm?
Solution :
The given values
bottom length a = 15 cm
top length b = 12 cm
height h = 10 cm
Step by step calculation
formula to find area = ((a + b)/2) h
substitute the values
= ((15 + 12)/2) x 9
= 121.5 cm2
The answer is 0.04 (I hope). Here is an explanation:
T = 2π√(l/g)
<span>=> T = 2π√[5m/(9.8m/s²)] </span>
<span>=> T ≈ 4,49s </span>
The answer for the question is 8.33
