Geometry Practice Test 1

Question : 16 of 40

Marks: +1, -0

The medians of ΔABC meet at G. If the area of the triangle is 120 sq. cm, then the area of the ΔGBC is:

Solution:

Area of ΔABC = 120

cm^2

Median divides the area of triangle into equal two parts.
AE, BG, CF are medians of ΔABC.

ar = (ar) = ar (ΔBGC) = ar (ΔBGA) = ar (ΔCGA)
Δ (BGC) =

1/3

or (ΔABC) =

{120}/3

= 40

cm^2
