<em>Answer:</em>
<em>56m</em>
<em>Step-by-step explanation:</em>
<em>Calculate each side's length.</em>
<em>Side A's length: 12m</em>
<em>Side B's length: 16m</em>
<em>Side C's length: 7m</em>
<em>Side D's length: 11m</em>
<em>Side E's length: 5m</em>
<em>Side F's length: 5m</em>
<em>5 + 5 + 7 + 11 + 12 + 16</em>
<em>10 + 7 + 11 + 12 + 16</em>
<em>17 + 11 + 12 + 16</em>
<em>28 + 12 + 16</em>
<em>40 + 16</em>
<em>56</em>
<em>Your answer is 56m.</em>

Answer:
27.84 m² , 42.48 m²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = bh ( b is the base and h the perpendicular height )
Shape A
has b = 9.6 and h = 5.8, then
A = 0.5 × 9.6 × 5.8 = 27.84 m²
Shape B
has b = 11.8 and h = 7.2 , then
A = 0.5 × 11.8 × 7.2 = 42.48 m²
