So you know that 1cm = 15 m in the diagram, and the width of the diagram's building is 6 cm. To solve, first you have to convert the 15 m to cm (centimeters) to make the measurements equivalent. There are 100 cm in 1 m, so you will multiply 15 x 100 = 1,500.
Now just multiply 6 x 1,500 to figure out how many cm the real wall is:
6 x 1,500 = 9,000 so the width of the real wall is 9,000 cm, but they want the answer in m (meters) so just divide 9,000 by 100:
9,000 ÷ 100 = 90 Your answer is 90 m. Hope this was helpful!
