Find the area of pentagon ABCDE.

Answer 1

20 sq.cm

Explanation:

Area of Pentagon ABCDE = area(ΔCBD) + area(rectangle AEDB)

Area of ΔCBD =
`(1)/(2) * height * base = (1)/(2) * 4 * 4 = (16)/(2) = 8 sq.cm`

Area of rectangle AEDB =
`length * breadth = 4 * 3 = 12sq.cm`

∴Area of Pentagon ABCDE = 8 + 12 = 20sq.cm
