Answer:

<h2>176 cm²</h2>

Step-by-step explanation:

you have a square and 4 equal triangles, you find the area of all, and you sum.

square area = l²

8² = 64 cm²

triangle area = b*h/2

8 * 7 : 2 = 28 cm²

now we sum 1 square's area and 4 triangles' area.

64 + 28 + 28 + 28 + 28 = 176 cm²

or

64 + (28 * 4) = 176 cm²
