Step-by-step explanation:
Each rectangle is a step. We'll start with the top one. This is simple: 6 times 3.
The farthest left is 5 times 3.
The crossed one is 6 times 5.
The one to the right of the crossed one is 3 times 5, again.
The farthest right is 6 times 5, again.
The bottom one is 6 times 3, again.
Now, we add.
1.3 x 0.4 x 2 = 1.04
0.5 x 0.4 = 0.2
(
(0.5 x 1.2)) x 2 = 0.6
1.04 + 0.2 + 0.6 = 1.84m²
0.5 x 0.4 = 0.2
(
1.04 + 0.2 + 0.6 = 1.84m²
