Answer:
<u>Trapezoid area:</u>
- A = 1/2(a + b)h, where a, b - bases , h - height
<h3>17. a)</h3>
- a = RS = 4 units
- b = AT = 8 units
- h = 8 units, the distance between RS and AT
A = 1/2(4 + 8)*8 = 48 units²
<h3>17. b)</h3>
- a = SK = 4 units
- b = OC = 10 units
- h = SO = 6 units
A = 1/2(4 + 10)*6 = 42 units²
<h3>18. a)</h3>
- a = ME = 6 units
- b = AZ = 10 units
- h = MA = 8 units
A = 1/2(6 + 10)*8 = 64 units²
