Two diagonals of a rhombus are 72 cm and 30 cm respectively. What is its perimeter?	Choose the correct answer:	A) 136 CM	B) 156 CM	C) 144 CM	D) 121 CM	E) 126 CM
ALL SIDES OF RHOM156 CMUS ARE CONGRUENT LET PR = 72 SQ = 30 CM   PO = 0R = 72/1 = 36 CM SO = 0Q = 30/2=

<output>15</output>
15 CM   PQ= QR = RS = SP   = ROOT( 36^2 + 15^2) = RPPT(1296+225)=ROOT(1521) = 39 CM   PERIMETER = 4 * 39=

<output>156</output>
156 CM   ANSWER 156 CM
<result>B</result>
