The length of a bridge on a map is 1.5 cm. what is the actual length of the bridge in meters if the map is drawn at a scale of 1: 40,000.

Step-by-step explanation:

If the length of a bridge on a map is 1 cm,then the actual length = 40,000

If the length of a bridge on a map is 1.5 cm,then the actual length= 1.5 * 40000

= 60000.0 = 60,000 m

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
