Step 1: find the area of the base
A=l*w = 8.25*5.5 = 45.375
Step 2: find the perimeter of the base
P=2l+2w = 2(8.25) + 2(5.5) = 16.5 + 11 = 27.5
Step 3: find the surface area of the prism
SA=2A+Ph = 2(45.375) + 27.5(4.5) = 90.75 + 123.75 = 214.5
Hope this helps
Answer:

Step-by-step explanation:
x=-3
Answer:
d
Step-by-step explanation:
Perform indicated multiplication:
11c+3(-5c)+3(4d)
11c-15c+12d combine like terms
(11c-15c)+12d
-4c+12d factor
4(3d-c)
Answer: A
<u>Step-by-step explanation:</u>
≅ 
⇒ ∠XOY ≅ ∠ZOY
≅
since they are both a radius
≅
based on reflexive property
∴ ΔXOY ≅ ΔZOY by SAS
So,
≅
by CPCTC
ZY = 10.2 is given
so, XY = 10.2 by substitution property
