Question

in Fig. 10.16. the angle B4D and ADC are right angles and Ar is parallel to BC If AB = BC = 5 cm. and DC = 8 cm. Calculate the area of ABCX (SO)​

Answer 1

Answer:

20cm

Step-by-step explanation:

AX||BC

AB||XC. (between 2 || lines

ABCX is a || gram

AB=AX=XC=BC=5

DC=DX+XC=>DX=3

Therefore, AD=4cm. (Pythagoras theorem)

Ar. of ||gram = base×height= AD×XC=>5×4=20cm
