$\frac{1}{2} \times dc$

THEREFORE

1/2x4=2cm

BC=2CM

16.BCPQ is a quadilateral.

18.let

x-5=0

therefore

x=5

20.value of x is 2

3x-6=0

3x=6

x=2

21. 22-2=20

therefore

90/20=4.5

therefore cost of one pencil is 4.5 rupees

22.(2x-1)(x-1)

2x(x-1)-1(x-1)

2x²-2x-x+1

this is the answer

23.(a-b)(a-b)

=(a-b)²

=a²+b²-2ab
