A city wants to create a garden, According to the plan below... Calculate the area of the garden.

Answer:
178 m²
Step-by-step explanation:
You want to find A - D - B + C
A = 12 * (12 + 4) = 12 * 16 = 192
D = 4 * 8 = 32
B = 4 * 3 / 2 = 12 / 2 = 6
C = 6 * 8 / 2 = 48 / 2 = 24
192 - 32 - 6 + 24 = 160 - 6 + 24 = 154 + 24 = 178
