Question
The triangular swimming pool shown is surrounded by a concrete patio. Find the area of the patio. Round to the nearest tenth if necessary. (Unit = square m.)
- 41
- 49
- 53
- 35
The correct answer is: 41
41 sq m
We need to find the area of the patio.
If we subtract the area of the inner triangle from the outer triangle, we’ll get our required result.
Area of outer triangle = ½ x 14 x 12.1 = 84.7 sq m
Area of inner triangle = ½ x 10x 8.7 = 43.5 sq m
Area of patio= 84.7- 43.5 sq m = 41.2 sq m
On rounding off to the nearest tenth, we get 41 sq m.

Identify the shape that will be angled cross-section of a rectangular pyramid.
The plane cuts the pyramid at an angle which is not parallel to the base of the cone, this is the reason why we are getting a rectangle but with a length : breadth ratio different than that of the base.

Name the shape that would result from slicing a rectangular pyramid parallel to the base
Since the pyramid is rectangular, this means that the base of the pyramid is a rectangle. Therefore, if we slice it parallel to the base, we’ll get a cross section which will look like the base of the pyramid, i.e., a rectangle.
