Min-jee is planting two rectangular flower beds. one bed is 2.78feet by 4.81feet, and the other bed is 2.78feet by 5.61feet. which expression does not represent the total area in square feet of the two beds?

Area of the rectangle is given by formula

Area = length * width

Then area of bed having dimension 2.78feet by 4.81feet will be:

Area1= 2.78*4.81 = 13.3718 square feet.

Area of bed having dimension 2.78feet by 5.61feet will be:

Area2= 2.78*5.61 = 15.5958 square feet.

Now add both areas to find total area

Total area = 13.3718 +15.5958 = 28.9676

We have to find which choice does NOT represent the total area.

Choices are not given so you just have to pick choice which is not same as 28.9676 square feet.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
