The answer is <span>he lengths of the bases of the trapezoids are
trapezoid A
b=19cm, and B=35cm, b the short base and B the long base
trapezoid B
</span><span>b=19cm, and B=35cm, b the short base and B the long base
</span>
the height is h=15cm
the surface of A is A= hx(b+B) /2
so the surface is A= 15(19+35)/2=405cm²
we know that suface A =surfaceB, so Surface B= 405cm²
finally the total surface painted is 2 x 405cm²= 810cm²
the perimeter of the trapezoid A is PA=17+19+35+17=88cm
<span>the perimeter of the trapezoid B is PB=17+19+35+17=88cm
</span><span> one piece of sandpaper will not be enough to sand the edges of one trapezoid</span>
