27 square meters
Step-by-step explanation:
Let's find the scale ratio.
0.15m = 15cm
15 ÷ 2 = 7.5
The scale ratio is 1:7.5 This means every 1 cm in the drawing is equal to 7.5 cms in real life.
Now let's find the length.
24 × 7.5 = 180. The actual length is 180 cm.
So our measurements are now 15cm by 180cm. Let's find the area:
15 × 180 = 2,700
Now let's convert cm to m. One meter = 100 centimeters so we'll divide by 100.
2,700 ÷ 100 = 27
The area of the quartz layer section is 27 square meters.
