Answer:
The answer to your question is Al = 46.36 cm²; A = 222.36 cm²
Step-by-step explanation:
Data
length = 11 cm
width = 8 cm
height = 1.22 cm
Process
1.- Calculate the lateral area
Al = 2(length x height) + 2(width x height)
-Substitution
Al = 2(11 x 1.22) + 2(8 x 1.22)
-Simplification
Al = 26.84 + 19.52
-Result
Al = 46.36 cm²
2.- Calculate the base area
Ab = 2(11 x 8)
Ab = 176 cm²
3.- Surface area
A = 46.36 + 176
A = 222.36 cm²
