Question:
Tick (✓) the correct answer:
In a square ABCD, AB = (2x + 3) cm and BC = (3x − 5) cm. Then, the value of x is
(a) 4
(b) 5
(c) 6
(d) 8
Solution:
(d) 8
$A l l$ the sides of a square are equal.
$\therefore A B=B C$
$\Rightarrow 2 x+3=3 x-5$
$\Rightarrow 3+5=3 x-2 x$
$\Rightarrow 8=x$
Therefore, the value of $x$ is 8 .
