Question 2 (d)
Find the area of the following triangle:
We know that the area of a triangle = 12×base×height Here, base = 3 cm and height = 2 cm ∴ Area of the triangle =12×3×2=3 cm2
In a given square ABCD, if the area of triangle ABD is 36 cm2, find (i) the area of triangle BCD; (ii) the area of the square ABCD.
