To find surface area, you can find the area od all sides and add them together
First, area of an triangle is 1/2 length times width
So you do 1/2 6*9= 1/2 54= 27 The area of the three triangles are 27
27 times 3 is 81
81 plus the base of 15.6 is 96.6
The surface area is 96.6 meters squared
Well it's 33. The 5 step problem thing I'm not to sure of.
Answer:
a = -8
Step-by-step explanation:
-5⁄2 a + 5 = 25
Subtract 5 from each side
-5⁄2 a + 5-5 = 25-5
-5/2 a = 20
Multiply each side by -2/5 to isolate a
-2/5 * -5/2 a = -2/5 *20
a = -8
