p+p-q+q+q-p

P+q

Answer 2

Answer:

11.   3cm²

12.  p+q

13.  10³

Step-by-step explanation:

11. Area of triangle = $\frac{1}{2}$*bh sq. units

    given the base, b ie.,BC = 3cm

              &    height,h ie.,AD = 2cm

   => area of the triangle = $\frac{1}{2}$ * 3*2 cm²

                                         = 3cm²

12.  simplify: p + (p-q) + q + (q-p)

                 = p + p - q  + q + q - p

                 = p+q

13. The exponential form of 1000 is = 10*10*10 = 10³
