An elevator building code requires at least 2.3 square feet per person. the depth of an elevator box is 7 feet. how wide must the elevator be to legally accommodate 15 people?

x = 4.9285 ft

Explanation:

q = 2.3 ft²/person

y = 7 ft

n = 15 persons

We can apply the formula

A = x*y

or

A = q*n = (2.3 ft²/person)*(15 persons)

⇒  A = 34.5 ft²

then we have

A = x*y  ⇒  34.5 ft² = x* 7 ft

⇒ x = 34.5 ft² / 7 ft

⇒ x = 4.9285 ft  (wide)

no

explanation:

since the earth is flattened at the poles and bulges at the equator, geodesy represents the figure of the earth as an oblate spheroid. the oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.
