Answer:
The area of trapezoid is 32cm².
Step-by-step explanation:
Given that the area of trapezoid formula is A 1/2×(a+b)×h where a, b represents length and h is height :
[tex]A = \frac{1}{2} \times (a + b) \times h [/tex]
[tex]let \: a = 4,b = 12,h = 4[/tex]
[tex]A = \frac{1}{2} \times (4 + 12) \times 4[/tex]
[tex]A = \frac{1}{2} \times 16 \times 4[/tex]
[tex]A = 8 \times 4[/tex]
[tex]A = 32 \: {units}^{2} [/tex]
