Answer:
one trapezoid has the area of 30 cm² and they have 60cm² of area when combined
to get the area of a trapezoid we have:
[tex] \frac{a + b}{2} \times h[/tex]
[tex] \frac{9 + 6}{2} \times 4[/tex]
[tex]15 \div 2 \times 4[/tex]
[tex]7.5 \times 4[/tex]
[tex] = 30c {m}^{2} [/tex]
since we have two trapezoid, we have to multiply our answer to two which will make it become 60cm²
