Question in MfEP Progress Quizzes
This question is an application of a quadratic equation. Student is given dimensions of a rectangular area, and an area of pavers that are available. They are asked to calculate the width of a border that can be paved around the given rectangle (assuming border is the same width on all 4 sides). The equation for the area of the border is given in terms of the unknown border width. Students need to recognise that only one solution of the quadratic gives a physically possible solution.
The dimensions of the rectangle, available area of tiles and type of space are randomised. Numeric variables are constructed so that resulting quadratic equation has one positive and one negative root.

Question in Demos
In four parts, the student builds up the definition of a class representing a rectangle. First they write the constructor, then add methods to compute area and perimeter.
In the final part, they must use the methods to write a function which determines if a rectangle's area is larger than its perimeter.

Question in Engineering Statics
Find the centroid of a shape made up of a rectangle and two triangles.
-
Question in Standard Maths
Students explore the relationship between length and area of a rectangle.
The perimeter of the rectangle is randomised. Students are given 11 different lengths, and asked to compute rectangle width and area for each. They are then asked to graph the function, identify it as a parabola, and estimate the maximum value.

Question in Engineering Statics
Calculate the centroidal moment of intertia of a rectangle with a excentric rectangular hole.
-
Question in Engineering Statics
Calculate the moment of inertia of a composite shape consiting of two rectangles about the x or y-axis. Parallel axis theorem is often required.
-
Question in Engineering Statics
Use the parallel axis theorem to find the area moment of inertia of a triangle and a rectangle about various axes.
-
Question in Engineering Statics
Find moment of inertia wrt the x- and y- axes for a shape made up of two rectangles.
-
Question in Engineering Statics
Find moment of inertia of a composite shape consisting of a rectangle and two triangles with respect to the x-axis. Shapes rest on the x-axis so the parallel axis theorem is not required.
-
Question in Engineering Statics
Use a table of properties to find the Area Moment of inertia for simple shapes: rectangle, triangle, circle, semicircle, and quarter circle.
The parallel axis theorem is not required for any of these shapes. One situation requires subtracting a triangle from a rectangle however.
Distinguish between centroidal and non-centroidal moments of inertia.

Question in Transition to university
This question tests the students ability to calculate the area of different 2D shapes given the units and measurements required. The formulae for the areas are available if required but students are encouraged to try to remember them themselves.
The shapes are: a rectangle, a parallelogram, a right-angled triangle, and a trapezium.
