In the figure above, ABCD is a square of side 18 cm and `bar(PN) bot bar(BC) and bar(PM) bot bar(AB)`. Find the length of MN.

In the figure above, ABCD is a square of side 8 cm and bar(PM) bot bar(AB) . Find the length of MC.

If ABCD is a square, then bar(AB) + 2 bar(BC) + 3 bar(CD) + 4 bar(DA) =

In the figure above, ABCD is a parallelogram, bar(BE)bot bar(AB), bar(BG)bot bar(CD) , and EBGD is a square. If BG=12 cm and BC=13 cm , then find AB.

In the figure 11.34, ABCD is a quadrilateral in which bar(AB) = bar(AD) and bar(BC) =bar(DC). Diagonals bar(AC) and BD intersect each other at O.Show that-

length of bar(AP)=3cm and bar(BP)=bar(AP) in the figure. Then length of AB is?

ABCDEF is a regular hexagon. If bar(AB)=bar(a), bar(BC)=bar(b)" then "bar(FA)=
