Alright......so the area of big square is 60×60=3600 cm^2. Smaller square has length 60–12 = 48 cm so area = 2304 cm^2. Difference between the larger and the smaller square is the area of four trapeziums. So the area of one trapezium is (3600 –2304)/4 = 324 cm2.

(Big box area - small box area)/4 So (60x60 - 48x48)/4

You could also do avg length of top and bottom side of the trapeze x height so (60+48)/2 x 6

thank You so much for providing 2 ways(of solving) that check out!

Omg… this is so simple and makes so much sense and I didn’t even think of it 😭. Thanks so much!

>It also says that the distance between the 2 squares is 6 cm. Edge-to-edge or corner-to-corner distance?

Edge to edge. It doesn’t say about corner to corner

You have the length of one of the parallel sides and the height. Can you find the length of the other parallel side?
