These are the steps:
1. Find area of the two triangles.
2. Find area of the rectangle.
3. Add them up.
<u>Step 1: Find area of the two triangles:</u>
Formula : Area of triangle = 1/2 x base x height
Both triangles are identical.
Height = 5m
Base = 6 + 6 + 12 = 24
Area = 1/2 x 24 x 5 = 60 m²
<u>Step 2: Find the area of the rectangle:</u>
Formula : Area = Length x Width
Area = 12 x 7 = 84 m²
<u>Step 3: Find the total area:</u>
60 + 84 = 144 m²
Answer: 144 m²
Add 
to both sides:
Add the fractions in the left hand side:
So, the equation becomes
Multiply both sides by 10:
Divide both sides by 9:
-3/4 because it's negative and also you can work it out by using rise/run
Answer:
F(40)=57.13
Step-by-step explanation:
0.015(40)=.6
.6+56.53=57.13
