Question

25. The area of ​​a large square is 16 cm2, and the area of ​​each small square is 1 cm2. Find the face of the painted area in the shape of a flower? (cm2 )​

Answer 1

The area of ​​the painted part is equal to the area of ​​the large square minus 4 areas of the small square minus 4 areas of the triangles.

area of the triangles = $\frac{1}{2} *2*2=2$

area=16-4*1-4*2=16-4-8=4 cm²
