Question

the side length of square jklm is 28 centimeters. what is the perimeter of square jklm? what is the area of square jklm? use the given information to complete the worksheet. calculating area of rectangles side of square jklm perimeter of square jklm area of square jklm diagram label kl value units 112 centimeters 784 square centimeters area formulas • parallelogram: a = bh • square: a = s² • triangle: a = 1/2 bh • trapezoid a = 1/2 h(b₁ + b₂)

Explanation:

Step1: Recall perimeter formula for square

The perimeter formula of a square is $P = 4s$, where $P$ is the perimeter and $s$ is the side - length. Given $s = 28$ cm.
$P=4\times28$

Step2: Calculate the perimeter

$P = 112$ cm

Step3: Recall area formula for square

The area formula of a square is $A=s^{2}$, with $s = 28$ cm.
$A = 28^{2}$

Step4: Calculate the area

$A=784$ $cm^{2}$

Answer:

Perimeter: 112 cm, Area: 784 $cm^{2}$
