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.
