Answer:
<h3>#1</h3>
<u>Trapezoid</u>
- A = (b₁ + b₂)h/2
- A = (4.8 yd + 29.4 ft)(8 yd)/2 = (14.6 yd)(4 yd) = 58.4 yd²
<h3>#2</h3>
<u>Rectangle</u>
- A = ab
- A = 2 yd * 3.1 yd = 6.2 yd²
<h3>#3</h3>
<u>Equilateral triangle</u>
- A = √3/4a²
- A = √3/4(10²) = 25√3
<h3>#4</h3>
<u>Regular octagon</u>
- A = aP/2
- A = 14.5(12*8)/2 = 696
8(51) = 8(50 + 1) = 8(50) + 8(1) = 400 + 8 = 408
Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55
