In the given figure, find the area of ΔGEF.
Given: (1) ABCD is a rectangle.
(2) CD = 6 cm
(3) AD = 8cm
To find: Area of ΔGEF.
Calculation: We know that,
Area of Parallelogram = base × height
If a triangle and a parallelogram are on the same base and between the same parallels , the area of the triangle is equal to half of the parallelogram
Here we can see that Parallelogram ABCD and triangle GEF are between the same base and same parallels.
Area of ΔGEF = `1/2` Area of Parallelogram ABCD
`= 1/2 xx AD xx CD `
`= 1/2 xx 8 xx6`
= 24 cm2
Hence we get the result as Area of ΔGEF = 24 cm2
