Question

what is the perimeter of parallelogram lmno? 18 cm 22 cm 40 cm 80 cm

Explanation:

Step1: Recall parallelogram property

In a parallelogram, opposite - sides are equal. Let \(LM = ON\) and \(LO=MN\). Given \(LM = 22\) cm and \(MN = 18\) cm.

Step2: Use perimeter formula

The perimeter \(P\) of a parallelogram is \(P = 2(a + b)\), where \(a\) and \(b\) are the lengths of two adjacent sides. Here \(a = 22\) cm and \(b = 18\) cm. So \(P=2(22 + 18)\).

Step3: Calculate the perimeter

First, add the values inside the parentheses: \(22+18 = 40\) cm. Then multiply by 2: \(2\times40=80\) cm.

Answer:

80 cm
