on a map with a scale of 2 cm = 25 km, what would be the dimension of a 145 km by 80 km rectangle?
acale= 2cm *145/25
scale= 2cm*80/25
those are the two new dimensions.
Thank you so much
Thankss !
To find the dimensions of a 145 km by 80 km rectangle on a map with a scale of 2 cm = 25 km, we can use the concept of proportions.
First, we need to determine the scale factor, which represents the ratio of distance on the map to the actual distance. In this case, the scale factor is 25 km / 2 cm.
To find the dimension of the rectangle on the map, we multiply the actual dimensions by the scale factor. Let's do the calculations:
For the length of the rectangle:
145 km * (scale factor)
145 km * (25 km / 2 cm) = 29 * 25 cm
= 725 cm
For the width of the rectangle:
80 km * (scale factor)
80 km * (25 km / 2 cm) = 16 * 25 cm
= 400 cm
So, the dimension of the 145 km by 80 km rectangle on the map would be 725 cm by 400 cm.
