Question

you buy invitations for a party. each invitation is a rectangle. the length of each card is 5.8 inches and the width is 3.5 inches. what is the area of each card? what is the perimeter of each card? use the given information to complete the worksheet. area formulas: parallelogram: a = bh square: a = s² triangle: a = 1/2 bh trapezoid: a = 1/2 h(b₁ + b₂)

Explanation:

Step1: Recall area formula for rectangle

The formula for the area of a rectangle is $A = l\times w$, where $l$ is the length and $w$ is the width.

Step2: Substitute given values

Given $l = 5.8$ inches and $w=3.5$ inches. So $A=5.8\times3.5 = 20.3$ square - inches.

Step3: Recall perimeter formula for rectangle

The formula for the perimeter of a rectangle is $P = 2(l + w)$.

Step4: Substitute given values

$P=2(5.8 + 3.5)=2\times9.3 = 18.6$ inches.

Answer:

Area of each card: 20.3 square inches
Perimeter of each card: 18.6 inches
