Area of Triangle
Five MCQs on Area of Triangle. Pick an answer, see the specific misconception. The diagnosis comes after the score.
The figure shows a right-angled triangle PQR where PQ is perpendicular to QR. PQ = 24 cm and QR is twice as long as PQ. Find the area of triangle PQR.
A square of side 12 cm has two diagonals drawn. The diagonals divide the square into 4 identical triangles. A circle is inscribed in ONE of the four triangles, just touching all three sides of that triangle. Estimate the AREA of the triangle (one of the four).
ABCD is a rectangle with AB = 8 cm and BC = 15 cm. Point E lies on side AD such that AE = 6 cm. Find the area of triangle BCE.
Triangle PQR is an obtuse triangle. QR = 14 cm is the base. Vertex P is positioned such that the perpendicular from P does not land inside the triangle — it falls on the extension of QR beyond R. The perpendicular distance from P to line QR (measured outside the triangle) is 6 cm. The slant side PQ measures 9 cm. What is the area of triangle PQR?
