A scale drawing for a backyard is shown below. In the drawing, 3cm represents 5m. Assuming the patio is rectangular, find the area of the real patio. Patio Lawn 6cm 3cm 12cm 3cm

1) As 3cm represents, is equivalent to 5 m
We can write:
3 cm ------------ 5m
6cm ------------ 5 x 2 = 10m
12cm -------------5 x 4 = 20m
2) Now, since we want the Patio area, we can write:
A = b * h
A = 5 x 10
A = 50 m²
3) Hence, the area of that patio is 50m²
