Question

2 - 107. this problem is a checkpoint for calculating areas and perimeters of complex shapes. it will be referred to as checkpoint 2. homework help for each figure below, calculate the area and the perimeter. a. parallelogram

Explanation:

Step1: Recall area formula

The area formula for a parallelogram is $A = base\times height$. Here, the base is $16$ cm and the height is $9$ cm.
$A=16\times9$

Step2: Calculate the area

$A = 144$ cm²

Step3: Recall perimeter formula

The perimeter of a parallelogram is $P=2(a + b)$, where $a$ and $b$ are the side - lengths. Here, $a = 16$ cm and $b = 10$ cm.
$P = 2(16+10)$

Step4: Calculate the perimeter

$P=2\times26=52$ cm

Answer:

Area: $144$ cm², Perimeter: $52$ cm
