Question

SILK is a rectangle. P is the point of intersection of the diagonals. KP=3-1cm and PL=2y+1,the length of SL= __ __ cm

Answer 1

Step-by-step explanation:

2y-1--34-1

2y--34

y--34/2

y--17

Answer 2

Answer:

Step-by-step explanation

KP = PI = SP = PL as all diagonals in rectangle are equal

So then, 3y-2+3y-2 = 2y+2+2y+2  6y-2 = 4y+2

6y-4y = 2+2

2y = 4

y = 4/2

y = 2/1 or 2

KP = 6-1 = 5

KP = PI = SP = PL = 5

So from this information:-

SL = SP+PL or 5+5

So SL = 10cm
