sec. ex. 17ab - 6.1 exercise 17b
each large square represents 5 unit(s)?

Explanation:

Step1: Define large square value

Each large square = 5 units

Step2: Calculate large squares total

$2 \times 5 = 10$

Step3: Define vertical bar value

First, find 1 bar value: $\frac{5}{10} = 0.5$

Step4: Calculate vertical bars total

$4 \times 0.5 = 2$

Step5: Define small square value

First, find 1 small square value: $\frac{5}{100} = 0.05$

Step6: Calculate small squares total

$7 \times 0.05 = 0.35$

Step7: Sum all components

$10 + 2 + 0.35 = 12.35$

Answer:

12.35
