Sagot :
Answer:
98 cm²
Step-by-step explanation:
Lateral surface area = surface area of the sides ONLY of the object
⇒ lateral SA = B + C + D = 35 + 28 + 35 = 98 cm²
For finding surface area we will add them all.
Surface area
[tex]\\ \rm\hookrightarrow A+B+C+D+E[/tex]
[tex]\\ \rm\hookrightarrow 10+35+28+35+10[/tex]
[tex]\\ \rm\hookrightarrow 118cm^2[/tex]
As we need LSA so let out A and E
- LSA=118-20=98cm^2
