ABCD parallelogram AD = 12 cm BOC perimeter is 27 cm. Find AC + BD.

Given:

ABCD parallelogram

AD = 12 cm;

BC = AD;

AC + BD -? cm.

P (BOC) = 27 cm;

The perimeter is calculated by the formula: P = 2 * (a + b) – where, a is the length, b is the width. Based on this, in relation to this task:

P (BOC) = BC + 1/2 BD + 1/2 AC = BC + 1/2 (BD + AC);
ВD + AC = (P – BC) * 2 = (27 – 12) * 2 = 15 * 2 = 30 (see)

Answer: 30 cm. ВD + AC.
