Ọ bụrụ na ọ bụ 5 ụkwụ n'obosara ọ bụ 9 ụkwụ n'ịdị elu n'ihi na 45 / 5 = 9. Ya mere, azịza ya bụ 9. <eng> Each 5 by 5 painting is 25 square feet because 5 x 5 = 25. All three of them take up 75 square feet because 3 x 25 = 75. The 10 by 8 painting takes up 80 square feet because 10 x 8 = 80. These four paintings take up 155 square feet because 80 + 75 = 155. The final painting is 45 square feet because 200 - 155 = 45. If it is 5 feet wide it is 9 feet tall because 45 / 5 = 9. So, the answer is 9.
