Question 4 : In the triangle PQR, S is the midpoint of QR. X is any point on PR. T is the point on QR such that PT || SX. If the area of triangle PQR is 5.8 sq. cm. then the area of triangle RTX is

1. 2.9 sq. cm
2. 3.2 sq. cm
3. 5.8 sq. cm
4. 2.45 sq. cm

Explanatory Answer

S is the midpoint of QR
Area of PSR = 1/2 x Area of triangle PQR [ median divides the triangle into two equal parts]
= 1/2 x 5.8 = 2.9
PT || SX
Area of triangle PSR = area of triangle PSX + area of triangle XSR
= area of triangle TSX + area of triangle XSR [triangles with vertices between two parallel lines have equal areas]
= area of triangle RTX = 2.9 sq cm

The question is " In the triangle PQR, S is the midpoint of QR. X is any point on PR. T is the point on QR such that PT || SX. If the area of triangle PQR is 5.8 sq. cm. then the area of triangle RTX is "

Hence, the answer is '2.9 sq. cm'

Choice A is the correct answer.
