Because the shape is a cube, we know that all sides must be 5cm. To find the area of a side, you do base × height, so 5 × 5 = 25. If you look at the net, you'll notice that there are 6 faces, which means you have to do 25 × 6 = 150cm^2. I hope this helps!
Find the scale between sides xz and gh
18/4 = 4.5
Multiply the length of fh by the scale to find x
6 x 4.5 = 27
x = 27
8 ÷ 11 = 0.72727272...
Therefore, decimal '72' is repeating
100x - 200 > 50x - 75
100x - 50x > -75 + 200
50x > 125
x > 2,5
Good Luck
