What are the answers to page 93 of Holt California Geometry Review for Mastery Workbook?

Answer 1

For Page 93 #9 It Says Find The Perimeter And Area Of Parallelogram TUVW. The Perimeter Is P=103cm. The Area Is A=472.5cm^2 <-- (Squared).

If You Want To Show Your Answer, Then To Find The Perimeter You Put 72 Over P Then You Put The = Sign And Put 2 Over 3. It Would Be A Proportion. Then You Cross Multiply 2 Times P = 2P And 72 Times 3 = 216. So Now You Will Have 2P=216. Then You Divide 2 To Both Sides. Then Your Final Answer Would Be P=103cm.

To Solve For Area, You Put 315 Over A Then The Equal Sign (=) Then 14 Over 21. You Will Then Have A Proportion. So You Cross Multiply. You Multiply 14 Times A= 14A Then You Multiply 315 Times 21, Which Equals 6,615. You Then Will Have 14A=6615. You Divide 14 To Both Sides And Your Final Answer Will Be A=472.5cm^2 (Squared). Make Sure To Put The Squared Signs Because We're Dealing With Area.
