If the diagonal of a rectangle is 17cm long and its perimeter is 46 cm. Find the area of the rectangle?	Choose one
A) 122 sq.cm	B) 120 sq.cm	C) 277 sq.cm	D) 118 sq.cm	E) 119 sq.cm
let length = x and breadth = y then   2(x+y) = 46 x+y = 23   x²+y² = 17² = 289   now (x+y)² = 23²   x²+y²+2xy= 529   289+ 2xy = 529   xy = 120   area = xy = 120 sq.cm   Answer: 120 sq.cm
