4+2=6 then you bring the 6 to the other side so you have combine like terms. 6-6=0 so its 0
Find the area and perimeter of the following triangle with the given vertices:
(1, 2), (8, 2) and (3, 6)
Explain your reasoning; show all your work for full credit!
3 inches and 2 inches, 6÷3 & 9÷3.
12×3=36 so divide 6 by 3 and 9 by 3
Answer:
shaded area = total area - the two triangles areas
total area = 5*9 = 45 cm²
first tri area = 1/2 * h *b
= 0.5 * 5 * 2 = 5 cm²
second tri area = 0.5 * 6 * 5 = 15 cm²
shaded area = 45 - 15 - 5 = 25 cm²
