7.5 squared units
Step-by-step explanation:
[tex]b_1 = 4\: units, \:\: b_2 = 1 unit \:\: h = 3 \: units \\
Area\: of \:Trapezoid = \frac{1}{2} \times (b_1 + b_2) \times h \\ \\ = \frac{1}{2} \times (4 + 1) \times 3 \\ \\ = \frac{1}{2} \times 5 \times 3 \\ \\ = \frac{1}{2} \times \times 15 \\ \\ = 7.5 \: {units}^{2} [/tex]
