Q. 6

In Fig. given below, find the area of ΔGEF.


Answer :

Given that,

ABCD is rectangle


CD = 6 cm


AB = 6 cm (opp. sides of rectangle)


AD = 8 cm


We know that,


If a rectangle and a parallelogram are on the same base and between the same parallels, then the area of a triangle is equal to the half of parallelogram


Δ GEF and parallelogram ABCD are on the same base and between same parallels.


Area of parallelogram = Base × Height


Now,


Area Δ GEF = 1/2 × Area of ABCD


= 1/2 × AB × AD


= 1/2 × 6× 8


= 24 cm2


Hence,


Hence area Δ GEF is 24 cm2.
