Answer 1

A=4x200000=800000 B=2x200000=400000

Answer 2

Calculating the Area of the Lake at a Scale of 1:200000

To calculate the area of the lake at a scale of 1:200000, we can use the given dimensions of the lake and apply the scale factor.

Given Dimensions: - Length: 4 cm - Width: 2 cm - Scale: 1:200000

Calculating the Actual Dimensions

To find the actual dimensions of the lake, we need to multiply the given dimensions by the scale factor.

Calculating Length: - 4 cm * 200000 = 800000 cm = 8000 meters

Calculating Width: - 2 cm * 200000 = 400000 cm = 4000 meters

Calculating the Area

Now that we have the actual dimensions of the lake, we can calculate the area using the formula: \[ \text{Area} = \text{Length} \times \text{Width} \]

Calculating the Area: - Area = 8000 meters * 4000 meters = 32000000 square meters

So, the area of the lake at a scale of 1:200000 is 32000000 square meters.
