Question

Min-Jee is planting two rectangular flower beds. One bed is 2.78 feet by 4.81 feet, and the other bed is 2.78 feet by 5.61 feet. Which expression does NOT represent the total area in square feet of the two beds?

Answer 1

(2.78 + 4.81) * (2.78 + 5.61)

Answer 2

Answer:

Option $(2.78 +4.81)\times (2.78 + 5.61)$ is the wrong representation of total area of flower beds.

Step-by-step explanation:

We are given the following information in the question:

Min-Jee have two rectangular flower beds,

Dimension for flower bed 1:

Length = 4.81 feet, Breadth = 2.78 feet

Dimension for flower bed 2:

Length = 5.61 feet, Breadth = 2.78 feet

Formula:

$\text{Area} = \text{Length}\times \text{Breadth}\\\text{Area of Flower bed 1} = 2.78\times 4.81\text{ square feet}\\\text{Area of Flower bed 2} = 2.78\times 5.61\text{ square feet}$

Total area of flower beds =

$(2.78\times 4.81) + (2.78\times 5.61)\\=2.78\times (4.81 + 5.61)\\=2.78\times 10.42\\=28.9676\text{ square feet}$

In the given image, Option $(2.78 +4.81)\times (2.78 + 5.61)$ is the wrong representation of total area of flower beds.
