solution please this question​

Answer 1

Answer:

144unit^2

Step-by-step explanation:

• Given figure is a combination of 2 right angle triangle
• Area of triangle whose hight = 15 and base = 15

=>area = h*b/2

=>area = ,15*15/2 =225/2unit^2

• area of Triangle whose hight is21 and base is 3

=>area = 21*3/2

=>area= 63/2

=>total area = 225/2 + 63/2 = 288/2 = 144unit^2

hope it may helps you:-)

Answer 2

Answer: 144 SQ UNITS

AR(ΔABC)=1/2 * BASE *HEIGHT

                = 1/2 * 15*15= 225/2= 112.5

AR(ΔADC)= 1/2 * BASE *HEIGHT

                = 1/2 * 21 *3=63/2=31.5

AR(ABCD)=AR(ΔABC)+AR(ΔADC)

                = 112.5 +31.5

                 =144
