A = 1/2h(b1 + b2)
2A = h(b1 + b2)
2A/h = b1 + b2
b1 = 2A/h - b2
Answer:
Multiply the number of inches on the map times the scale to determine the true distance. For example, if the distance on the map was 5.5 inches and the scale was 1:6,336,000, the true distance would be 550 miles. To convert an area, convert the dimensions using the scale and then find the true area.
I would say read it well and then write down an equation or expression to represent the data so its easier for you to understand and/or solve.
Answer:
1
Step-by-step explanation:
Given:
<u>Substitute the values into the expression:</u>
1/2(m - 4) × n
⇒ 1/2(12 - 4) × 1/4
<u>Simplify the expression:</u>
⇒ 1/2(8) × 1/4
⇒ 4 × 1/4
⇒ 4 ÷ 4
⇒ 1 (Option B)
