The volume is the product of the side lengths which is 1*6*11= 66 mm^3. The surface area is twice the sum of all the possible products of the side lengths, or 2lw+2wh+2hl which is 2(6*11+6*1+11*1) = 166 mm^2 if my mental math is decent.
M=(x1+x2/2, y1+y2/2)
M= (2, -4)
Answer:
136 square cm
Step-by-step explanation:
Area of rectangle = 18x7=126 square cm
Area of triangle = 1/2x(11-7)x(18-13) = 1/2(4)(5) = 10 square cm
126+10 = 136 square cm
Great, because y=2x+5 is 3xy kay.
