Perimeter of rectangle is calculated by taking the sum of all the sides of the rectangle. In rectangles the 2 opposite sides are equal
length - 3x - 1
breadth - 3x - 3
the formula used to calculate perimeter for rectangle
perimeter = (2 x length) + (2 x breadth)
substituting length and breadth
perimeter = {2 x (3x - 1)} + {2 x (3x - 3)}
= 6x - 2 + 6x - 6
= 12x - 8
therefore correct answer is

Step-by-step explanation:
The triangle can be any measure it just needs add up to 180.
Remember only one right angle.
Or isosceles which two angles are the same.
or equilateral. Which means all sides are the same .
251 rounded to the nearest hundred is 300
total surface area Stot = 1180 in2
lateral surface area Slat = 920 in2
top surface area Stop = 130 in2
bottom surface area Sbot = 130 in2
