Question

in the figure ABCD is a rectangle. AB =6 cm, AD =3 cm. P, Q and R are the points on the line DC. ADB, APB, AQB and ARB are the triangles whose base is AB and third vertices lie on the line DC. (a) what are the special features of the sides AB and DC Hi? (b) what is the area of the triangle ADB?​

Answer 1

Answer:

the value of adb is 985 when you add them

Answer 2

Step-by-step explanation:

$(a) \: special \: features \: of \: side \:{ ab} \: \\ and \: dc \: is \: that \: we \: can \: use \: this \: \\ sides \: to \: determine \: the \: value \\ of \: line \: (ad) \: using \: pythagoras \\ theorem.$

$(b) \: area \: of \: triangle \: adb \\ \\ \\ we \: know \: that \: area \: of \: triangle \: \\ = \frac{1}{2} \times base \times height \\ here \: ab = 6cm \\ and \: ad = 3cm \\ . \\ . \: \: \: \: \: \: . \\ \frac{1}{2 } \times ab \times ad \\ = \frac{1}{2} \times 6 \times 3 \\ = \frac{1}{2} \times 18 \\ = 9 {cm}^{2}$
