Question

calculate the shaded area​

Answer 1

Answer:

27 is the area of the cross

Step-by-step explanation:

If we divide the cross to 5 squares, each of the square has the side 3cm.

Area of a square = side×side

= 3×3

= 9

if one square has 9 as area, the remaining 4 squares will have:

9×4 = 27
