solniwko [45]

Answer:

The length of the diagonal AC=20 cm.

Step-by-step explanation:

From ΔOBP and ΔABC, we have

\frac{OB}{AB}=\frac{BP}{BC}( O and P are mid points)

∠B=∠B(Common)

Therefore, by SAS rule,

ΔOBP is similar toΔABC

Thus, \frac{OB}{AB}=\frac{OB}{2OB}=\frac{1}{2}

⇒\frac{OP}{AC}=\frac{1}{2}

⇒AC=2{\times}OP

⇒AC=2{\times}10

⇒AC=20 cm

Thus, the length of the diagonal AC=20 cm.
