= (4a+ 5 ) . ( a - 3 )

The length and breadth of a rectangle are in the ratio 4:3 .If the diagonal measures 25 cm .Find the perimeter of rectangle SOLUTION: Let the Length be 4x Let the Breadth be 3x According to Pythagoras theorem, (4x)²+(3x)²=(25)² 16x²+9x²=625 25x²=625 x²=625/25 X =5 So, Length = 4x = 20 cm Breadth = 3x = 15 cm Perimeter = 2(l×b) = 2 (20 + 15) = 70 cm So, perimeter of rectangle is 70 cm.
