Question
notation check: a rectangular poster has length 25 cm and width 23 cm. Find its area. Show your working one step at a time.
Answer
The final answer is 575 cm^2. Area measures the square units inside the rectangle. Use the rectangle area method with length and width. The length is 25 cm. The width is 23 cm. Multiply 25 by 23. 575 cm^2
Explanation
exam warm-up keeps the canonical answer 575 cm^2 fixed before the model answer is written, so the worked solution and final answer agree.
Common mistake
Constructions and loci common mistake 1
Writing a final answer without showing the method that justifies it. This can weaken answers for: [Foundation and Higher] Know that perpendicular distance from a point to a line is the shortest distance to the line..
Show the method first, then give the final answer in the required form. Apply this directly to Constructions and loci.
