Find the area and perimeter of fig ABCD where B=90 and angle DAC=90 degrees. AB=6cm and BC=8cm and DA=24cm
STALIN [3.7K]

Answer:

96\ \text{cm}^2

17.1\ \text{cm}

Step-by-step explanation:

DC is the length of the hypotenuse of the triangle CED.

So

DC=\sqrt{ED^2+EC^2}\\\Rightarrow DC=\sqrt{16^2+6^2}\\\Rightarrow DC=17.1\ \text{cm}

The perimeter of the ABCD is 17.1\ \text{cm}

AB+AD+DC+CB=6+24+17.1+8=55.1\ \text{cm}

The Area of ABCD would be

Area of rectangle ABEC+Area of triangle CED

8\times 6+\dfrac{1}{2}\times 16\times 6=96\ \text{cm}^2

The area of the figure ABCD is 96\ \text{cm}^2.
