Data:
• One base, ,( ,b1 ,): ,3.2 yards
,• Other base (, b2 ,):, 2.8 yards
,• Height ( ,h ,): ,4.3 yards
,• Packet of flower seeds ( ,P ,),: 5.5 square yards
Procedure:
0. Finding the area of the trapezoid ( ,At ,):
[tex]A_t=\frac{1}{2}\cdot(b_1+b_2)\cdot h[/tex][tex]\begin{gathered} A_t=\frac{1}{2}\cdot(3.2_{}+2.8_{})\cdot4.3=\frac{1}{2}\cdot(6_{})\cdot4.3=\frac{1}{2}\cdot25.8=12.9 \\ A_t=12.9 \end{gathered}[/tex]2. Finding the least number of packets Theresa would need to plant flowers in her flower bed:
[tex]\frac{12.9}{5.5}=2.35\approx2[/tex]Answer: 2 packages
