Answer:
Step-by-step explanation:
Join A and C and B and D. And add numbers to the angles formed on one of the diagonal
In triangles ABC and ADC,
Angle 1 = Angle 4
Angle 3 = Angle 2
AC = AC
Therefore, triangle ABC=ADC
Since, ABC=ADC
Similarly, triangle ABD= triangle CDB
Therefore, AB=CD and BC=DA
Answer:
(a x 4)+(a x 3)=7a
Step-by-step explanation:
(a x 4)+(a x 3)= 4a+3a
(a x 4)+(a x 3)=7a
