Answer:
Step-by-step explanation:
The equation to find the rectangle is given, so plug in the numbers for each variable. 1/2 is also 0.5, so multiply that by h, or in this case 6.
Then both bases are 8 (8 + 8 = 16)
That leaves you with 3 • 16 or (6 • 0.5) (16)
16 times 3 gives you 48.
The triangle is a bit trickier, but the equation is A = 1/2 bh
1/2 is once again 0.5, keep that to the side for now.
Plug in 10 for b (your base) and 6 for h (your height)
Multiplying these together gives you 60, multiplied by 0.5 is 30.
Add 48 and 30 together, you get 78 as the total area.
