Question

Find the area of each figure. Round to the nearest hundredth if needed.

Answer 1

Answer:

#1

Trapezoid

• A = (b₁ + b₂)h/2
• A = (4.8 yd + 29.4 ft)(8 yd)/2 = (14.6 yd)(4 yd) = 58.4 yd²

#2

Rectangle

• A = ab
• A = 2 yd * 3.1 yd = 6.2 yd²

#3

Equilateral triangle

• A = √3/4a²
• A = √3/4(10²) = 25√3

#4

Regular octagon

• A = aP/2
• A = 14.5(12*8)/2 = 696
