The value of the expression would be 16.25 or 16 and 1/4, because when you multiply something by 1/2, you’re basically dividing it by 2, and when you put parentheses next to a number (for example 2(4) ), it means that you’re multiplying it, and when more than one values are in the parentheses, they all get multiplied, basically distributive property.
Answer:
213 meters squared
Step-by-step explanation:
The surface area of a rectangular prism is found using the formula A=2(wl+hl+hw). Here substitute l = 6, w = 3.5 and h = 9.
A = 2((3.5*6) + (9*6) + (3.5*9))
A = 2(21 + 54 + 31.5)
A = 2(106.5)
A = 213
B. A quadrilateral equals 360, a triangle 180. 360-180=180
