If each side of a square is increased by 50% the ratio of the area of the resulting square to the area of the given square is__________?
Correct answer: B. 9:4
- A. 5:4
- B. 9:4
- C. 4:5
- D. 4:9Fun & Trivia
Explanation
Increasing each side by 50% makes the new side 1.5 times the original side. Area is squared, so the area ratio is (1.5)² : 1 = 2.25 : 1 = 9:4. The likely trap is 5:4, which treats the 50% side increase as though area increased by only 25%.

About Area and Volume
Area measures the surface enclosed by two-dimensional figures, while volume measures the space occupied by three-dimensional solids. Problems use formulas for rectangles, triangles, circles, prisms, cylinders, cones, spheres, and composite figures, including unit conversion and the distinction between surface area, lateral area, and volume.
