Answer:
y=2.6
Step-by-step explanation:
y/4=1.3/2
cross product
4*1.3=y*2
5.2=2y
y=5.2/2
y=2.6
To find the area of a triangle, multiply the height (6) by the base (4) and divide by 2.
- 6 • 4 = 24, 24 / 2 = 12.
The area of this triangle is 12.
I don't have the answer for the second one, but the answer to number 1 is 9.
6÷2(1 + 2) =
6÷2(3) =
3(3) =
9
