The Prairies stretch approximately how many kilometers from east to west?

• A. 1000 km
• B. 1500 kilometers
• C. 1700 km
• D. 1200 km

Answer: (B)

Estimating how wide a region is from east to west helps you grasp its scale and the extent of its landscape. The Prairies run across central North America, mainly through Alberta, Saskatchewan, and Manitoba, from the eastern edge near Manitoba’s boundary with Ontario to the western edge at the Alberta–British Columbia border. Measured as a straight-line distance on a map, this width is about 1,500 kilometers. That makes 1,500 kilometers a solid practical estimate for the prairie belt’s width. Shorter figures like 1,000 or 1,200 kilometers miss part of the span, while 1,700 kilometers would overstate it, though definitions of where the Prairies begin and end can shift the precise number.
