1.	9. M is the midpoint of the side AB of a parallelogram ABCD. If ar(AMCI= 24 cm, find ar(△ ABC)
Answer» AB = CD = 2b AX = BX = b Height = h Here AXCD is trapazeium has two parallel side (AX\|\|CD) The area of trapezium = 1/2 (AX +CD) x Height = 1/2 (b+2b) * h = 1/2 bh + bh From the question: 1/2 bh + bh = 24 --- (1) Area of triangle = 1/2 base x height 1/2 (2b) h = bh bh = 24 wrong hai

Answer»

AB = CD = 2b

AX = BX = b

Height = h

Here AXCD is trapazeium has two parallel side (AX||CD)

The area of trapezium = 1/2 (AX +CD) x Height

= 1/2 (b+2b) * h

= 1/2 bh + bh

From the question:

1/2 bh + bh = 24 --- (1)

Area of triangle = 1/2 base x height

1/2 (2b) h

= bh

bh = 24

wrong hai
