Find the area and perimeter of a square plot of land the length of whose diagonal is 14 metre . Give your answer correct to 2 places of decimals
ans.Area= 98 m2 , perimeter = 39.60 m
plz ans fast no links

Area = 1/2[D2] = 1/2x14x14 = 98 m2.   First Method.
Using Pytho Theorem  Side2 + Side2  = Diag2.
2Side2  = 142
Side2  = 196/2  = 98   [Thus  Area = 98 m2.]
Side  =  Root 98 = 9.90 m 
Perimeter = 4x9.90 = 39.60 m
