Answer:
The area of Figure ABCD is 25 square units
Step-by-step explanation:
we have
A(−3, 2), B(2, 2), C(2, −4), and D(−3, −2)
step 1
Plot the figure
using a graphing tool
The figure is a trapezoid
see the attached figure
step 2
Find the area of the trapezoid
The area of the trapezoid is equal to
![A=\frac{1}{2}[AD+BC]AB](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5BAD%2BBC%5DAB)
we have
---> difference in the y-coordinates
---> difference in the y-coordinates
---> difference in the x-coordinates
substitute
![A=\frac{1}{2}[4+6]5](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B4%2B6%5D5)

Complete question :
The garden club earned $15 per hour by weeding neighborhood gardens for tt hours. A generous donor has agreed to double their earnings. How much did the garden club earn in all? Write your answer as an expression.
Answer:
($15t × 2)
Step-by-step explanation:
Given the following :
Amount earned per hour = $15
Number of hours = t
Amount earned for t hours = (amount earned per hour × number of hours)
= (15 × t) = $15t
Doubling this amount means multiply the amount earned by 2
= $15t × 2 = $30t
Answer:
The volume of the solid is 420m³
Step-by-step explanation:
The area of any pyramid is "1/3 · B · h", where B is the area of the base, and h is the height.
Knowing this we just need to solve for a couple of things.
First, and the easiest is the height of the triangle which (thankfully) is given to us. The height is 15m, which plus one number into our equation.
1/3 · B · 15
Second, we need to find the area of the base of the pyramid. That's done easily by finding the area of a triangle (
→
→
→
) giving us 84 units. This puts another number into our equation.
1/3 · 84 · 15
Now that we have all of the parts to our equation, we can solve it.
1/3 · 84 · 15
1/3 · 1260
420
The volume of the solid is 420m³
L = 0 bcause it cancels itself out
