Question

in rectangle PQRS, SR 20 cm and PR 35 cm find .
a)= PQ. b)= SK​

Answer 1

PQ=SR(opposite sides in a rectangle are equal )
Therefore,PQ=20cm

Now,PR=SQ(diagonals of rectangle are equal )

SK=KQ(diagonals bisect each other)

Therefore SK=1/2SQ
SK=17.5 cm

Answer 2

a.PQ=20 cm

b.SK=17.5 cm

Step-by-step explanation:

In rectangle PQRS

SR=20 cm

PR=35 cm

Properties of rectangle

1.Opposite sides of rectangle are equal

2.Diagonals of rectangle are congruent

3.Each angle of rectangle is equal to 90 degrees

4.Diagonals of rectangle bisect to each other.

By property of rectangle

a.SR=PQ=20 cm

b.PR=SQ=35 cm

$SK=\frac{1}{2}SQ$

$SK=\frac{1}{2}(35)=17.5 cm$
