Answer:
367.2 cm²
Step-by-step explanation:
First, you need to find the area of the lateral surfaces, since each one is a 5cm by 6cm rectangle, all you need to do is multiply to find the area of one of them, and then multiply by 6 to find the area of all 6 sides.
lateral area = 5cm * 6cm * 6
lateral area = 30cm² * 6
lateral area = 180 cm²
Next, you need to find the total surface area by multiplying the area of the base by two and adding that to the lateral surface area.
SA = 180cm² + 2(93.6cm²)
SA = 180cm² + 187.2cm²
SA = 367.2cm²
The total surface area is 367.2 cm².
I think you multiply 1/2 by the x and y point
1/2(0)= 0
1/2(-6)= -3
(0,-3)
Check the picture below, let's use those two points on the line to get its slope.

182 Let x = width then y = 6x - 91. P (perimeter) = 2x + 2y = 84 then
2(x) + 2(6x - 91) = 84 | 2x + 12x - 182 =84 | 14x = 84 + 182 | 14x = 266 | x = 19 cm
y = 6x - 91 | y = 6 (19) - 91 | y = 114 - 91 | y = 23 cm
Check: P = 2x + 2y | P = 2(19) + 2(23) | P = 38 + 46 | P = 84 cm (Checked)
5 + x - 6 = 4
x= 5
5 plus 5 equals 10 and 10 minus 6 is equal to 4.
