Given that:
Height of the trapezoid, h = 24 in.
Bases are a = 48 in, b = 60 in.
Find the area of the trapezoid.
[tex]\begin{gathered} A=\frac{48+60}{2}\cdot24 \\ =54\cdot24 \\ =1296 \end{gathered}[/tex]
Number of tiles needed
[tex]\begin{gathered} =\frac{1296}{16} \\ =81 \end{gathered}[/tex]
So, 81 number of tiles needed to create the trapezoidal hearth.
