12*5*2=. 5*8=. 8*13=. 8*12=. Now times add all these up
All you'd have to do is multiply 20 cm2 by 5 cm because volume is cm3, so if the base is already giving you cm2, you'll need the last measure which is height.
The answer would be 100 cm3
Answer=176ft^2
Area of a square is l x w or 16 x 14=224
Area of a triangle uses the formula ab/2, so it would be 16 x 6/2=48
224-48=176
I dont really remember how to solve this since i done this some time ago the angles must be the same i would say d since 5 the bigger triangle is five times bigger

Answer:
The approximate length of the pendulum is 46.08 ft
Step-by-step explanation:
The time (t) of pendulum oscillation is given as;
where;
L is the length of the pendulum
g is acceleration due to gravity = 9.8 m/s² = 32.15 ft/s²
t is the time given as 2.4 π seconds
From the equation above, make L the subject of the formula;
Therefore, the approximate length of the pendulum is 46.29 ft
The closest option is 46.08 ft
