Question

PQRS is a rhombus with PS = 15 units and PR = 24 units

(please help me)

1) determine, with reasons, the length of QR

2) determine, with reasons, the length of b

Answer 1

QR = 15 units , b = 12 units

Explanation:

In a rhombus

• All sides are congruent (equal ) , then

(1)

QR = PS = 15 units

• the diagonals are perpendicular bisectors of each other , then

TR = b =
`(1)/(2)` PR =
`(1)/(2)` × 24 = 12 units

Answer 2

1) PQRS is a rhombus:

A rhombus is a quadrilateral whose four sides have the same length--->QS=SR=RQ=QP= 15 units

2) PQRS is a rhombus:

The diagonals of the rhombus intersect in the middle

b=1/2PR

b= 24/2 =12units
