Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4
Answer:
22m²
Step-by-step explanation:
The area of the bases is 3m²
The area of the left and right lateral faces is 2m²
The area of the front and back lateral faces is 6m²
The lateral area of the prism = (3m² x 2) + (2m² x 2) + (6m² x 2)
= 6m² + 4m² + 12m²
= 22m²
