To solve for the area of a triangle you use the formula A=b*h/2. The base for this triangle is 4 and the height is 8. Take 4*8 which is 32 and divide that answer in half to get 16 which is your answer.
Find how many cubic feet
cubic feet=length times width times height for rectangle prism
volume=30 times 20 times 5=3000 cubic feet
7.5 per 1 cubic feet
times 3000
22500 gallons
Answer:
The width of the door is 32 cm.
Explanation:
The formula for area is A = l*w
so the equation becomes:
1792 = 56*w
Divide both sides by 56 and you get
w = 32
Given that,
Charge q₁ = -0.004 C
Charge q₂ = -0.003 C
Distance between charges, d = 3 m
To find,
The electrostatic force between charges.
Solution,
The formula for the electrostatic force is given by :

So, 12000 N of electrostatic force is produced.
