Answer»

the cost of 12 pen is rupees 9 3/5

Yes.AQ= DP

Traingle ABQ and Traingle DAP are congruent with AQ and DP being hypotenuse.

cuxui8899cccfusxtzfiiiiibovo

yes AQ = DP because tiangle ANQ is congruent to triangle DAP

ab=bc( since it is a square)bp=cq (given)

ab+bp=bc+cqap=bq=3 cm

apply pythagorean theory for ADP triangle and ABQ trianglethen AQ=DP=√(2)sq+(3)sq=√13

the cost of pens its 9 3/5

RD Sharma ka question hai

BC=AB,So BQ=AP,DA=AB,so by

the cost of 12 pen is rupees 93/5

both are congruent by RHS

93/5 is the best answer

As , ABQ is congruent to DAP So , AQ=DP Hypotenuses

Triangle AQB Congruent Triangle ADP. (by SAS)

AQ = DP (by CPCT)
