This topic helps learners practice finding the area of a rectangle surrounding a right triangle. Each question presents a visual problem where the learner must calculate the area of the rectangle based on given dimensions. The problems include a variety of measurement units such as centimeters, inches, meters, and kilometers, allowing students to work within different measurement systems while reinforcing their understanding of area calculations. This exercise is a component of a larger unit introducing triangle areas, focusing on the introductory concepts of relating rectangle areas to right triangles.
