Question

Mark (✓) against the correct answer:
In a square PQRS, if PQ = (2x + 3) cm and QR = (3x − 5) cm then
(a) x = 4
(b) x = 5
(c) x = 6
(d) x = 8

Answer 1

(d) x = 8
All sides of a square are equal.


$$\begin{gathered} PQ=QR \\ (2x+3)=(3x-5) \\ =>2x-3x=-5-3 \\ =>x=8\mathrm{cm} \end{gathered}$$
