B + g = 42
b = 2/5g
2/5g + g = 42
2/5g + 5/5g = 42
7/5g = 42
g = 42 / (7/5)
g = 42 * 5/7
g = 210/7
g = 30 <== there are 30 girls
b = 2/5g
b = 2/5(30)
b = 60/5
b = 12 <=== there are 12 boys
Answer:
<h3>Minimum area: 6.75 km2, maximum area: 10 km2.</h3>
Step-by-step explanation:
We are given that a rectangle has length = 2km and width = 5km.
Formula for area is :
Area = Length × Width
Plugging values in above formula for area, we get
Area = 2km × 5km
On multiplying 2 and 5, we get 10.
Therefore,
So, the maximum area possible area is .
Therefore, you can choose correct option as:
<h3>Minimum area: 6.75 km2, maximum area: 10 km2.</h3>
