Question

The two sides of rectangle is x+2 and 4x the diagonal measures 13cm.

Answer 1

Answer:

length = x+2

breadth = 4x

diagonal = 13cm

ATQ diagonal² = lenght² + breadth²

diagonal² =( x+2)² + 16x²

diagonal² = x² +4 +4x +16x²

13² = 17x²+4x+4

17x²+4x -165=0

17x² + 55x -51x -165 =0

x= -55/17 or x= 3
