Question

11. Higher Order Thinking Cora makes this
design with square and triangular tiles.
What is the area of the design? How did
you calculate your answer?​

Answer 1

Step-by-step explanation:

With no photo of the design is imposible to calculate exactly the design area. However:

We know that the area of a square is:

$A_{sq}=L^2$ where L is the leght of the square's side

Also, the area a triangle is:

$A_{tr}=\frac{h*b}{2}$ where h is the height and b is the base (see the figure)

So, the total area, assuming that all square tiles are equal between them (the same for the triangular ones):

$A_{total}=A_{sq}*n_{squaretiles}+A_{tr}*n_{triangtiles}$
