Answer:
100 m²
Step-by-step explanation:
The scale drawing has dimensions 25 cm and 16 cm
The actual rectangles dimensions are 50 times greater, that is
length = 25 × 50 = 1250 cm ← divide by 100 to convert to m
length = 1250 ÷ 100 = 12.5 m
width = 16 × 50 = 800 cm
width = 800 ÷ 100 = 8 m
Actual area = 12.5 × 8 = 100 m²
Answer:
B
Step-by-step explanation:
Part A:
3(m+54) = 381 shows that 54 is being added to m, the initial sum. Then it shows the sum of 54 + m being multiplied by 3 to get to the new balance of $381. This equation most accurately matches with the question.
Part B:
3(m-54) = 381.
You would first divide both sides by 3.
m - 54 = 127
You would now add 54 to both sides.
You now know m = 181.
