Answer: 3.57
Step-by-step explanation: When you round the number 3.57 to the nearest tenth, you get 3.6.
Factor them
45=3*3*5
18=2*3*3
lcf=2*3*3*5=90
The area of the trapezoid can be calculated through the equation,
A = (b₁ + b₂)h / 2
where b₁ and b₂ are the bases and h is the height. Substituting the known values from the given,
A = (25mm + 32mm)(15 mm) / 2
A = 427.5 mm²
Since there are two trapezoids in the necklace, the area calculated is to be multiplied by two to get the total area.
total area = (427.5 mm²)(2)
<em>total area = 855 mm²</em>
