Question 2

ΔABC is similar to ΔPQR. Length of AB is 18 cm and length of the corresponding side PQ is 12 cm. If area of ΔABC is 324 sq cm, what is the area of ΔPQR?

Question 3

E is the mid-point of the median AD of . BE is joined and produced to meet AC at F. F divides AC in the ratio :

Question 4

For a triangle, base is cm and two base angles are 30 ° and 60. Then height of the triangle is

Question 5

A straight line parallel to the base BC of the triangle ABC intersects AB and AC at the points D and E respectively. If the area of ΔABE be 36 sq. cm then the area of ∆ACD is
