Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches

Answer:
Step-by-step explanation:
<u>Top base:</u>
<u>Left leg:</u>
<u>Bottom base:</u>
<u>Right leg:</u>
- c² = √6²+8² = √100
- c = 10 units
<u>Perimeter:</u>
- P = 6 + 8 + 10 + 12 = 36 units
12.4 because 62 divided by 5 = 12.4
