Question

Heather built a geometrically similar model of the Great Pyramid. The height of the actual pyramid is approximately 147 meters. Heather's model is 98 millimeters in height. The width of the base of the actual pyramid is 231 meters. Which measurement is closest to the width of the base of Heather's model?

Answer 1

so just use the rule of 3 simple and you can writing in this way

147 m mean 98 mm
231 m mean x mm and now cross multiplie and calcule the x value

x = 231 * 98 / 147 = ? mm
