Apart from joining S to y axis and joining S to x axis and making a rectangle…Is there any other way to solve this Q?
Join S to the origin so you’ll get two triangles.
- First triangle with RS as the base and a height of 4
- Second triangle with OT as rhe base and a height of 5

I got 5 SE wrong in my PPP+3 mock, any idea from where can I practice SE?
I am unable to visualize Geometry questions as this one above…like I could not visualize which all sides to join and how to get area of quad…any idea what can I do? Shall I solve Greg prep club geometry sums? Medium or hard ones?
I have my exam on 28th.
You can attempt geometry questions like this. Basically, ETS will not test you for anything other than foundational maths. In this question for example, They asked the area of the quadrilateral, but is that foundational math? No, we’ve never learnt any concepts to find areas of irregular polygons. So they are expecting you to simplify the problem into the math we already know. In this case, areas of triangles and rectangles. You can break the quadrilateral into shapes that you already know. The solution I provided was simply one of the many solutions.
Square + Triangles
An alternative would be to assume the square of side 3 (with the fourth vertex being, say P, at (3,3)). Now you have the area of the square, now break down the remaining portion of the quadrilateral. So you can now connect S to P and get two triangle with base RP and TP. Find those areas and proceed.
Rectangle - triangles
Another alternative would be what you started with. Let us extend point S to x and y axis to say points K and L. Now you know the area of the rectangle OKSL. Now from that, remove two triangles which are extra.
So, basically, ETS is only trying to trick you to be scared when the math is actually pretty simple. Just slow down, look at the question twice, and dissect it properly.
