A map is drawn to a scale of 1 : 240 000. (i) If a seawater lake has an area of 3.8 cm² on the map, find its actual area in square kilometres.

(ii) If the actual area of a plot of land is 2 908 800 m², calculate its area on the map.

answer

a the answer hopes this

step-by-step explanation:

[tex]Which table shows a proportional relationship?[/tex]

Agreed i also had the same answer

Step-by-step explanation:

Above are the explanations

[tex]A map is drawn to a scale of 1 : 240 000. (i) If a seawater lake has an area of 3.8 cm² on the map,[/tex]

(I)9.12×10-⁵km²

ii)12.12m²

Step-by-step explanation:

since the scale is 1:240000,the 1 represents the area on the map and the 240000 represents the area on the ground so to find the area on the ground for number 1 you use the scale and then convert your answer to km²

1 : 240000

3.8:x

x=912000cm²

then you convert it to km²

(100000cm)²:(1km)²

912000. 😡

(100000)²x/100000²=912000/(100000)²

x=9.12×10-⁵

then for the second one you use the same scale

1:240000

x:2908800

240000x/240000=2908800/240000

x=12.12m²

I hope this helps and sorry if it's wrong
