A school is building a rectangular stage for its chorus. The stage must have a width of 4 feet. The area of the stage must be at
slavikrds [6]

Answer: Length ≥ 6 feet

Step-by-step explanation:

The area of a rectangle= length × width

In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.

The inequality that describes the possible lengths (in feet) of the stage would be:

Length × Width ≥ 24

Length × 4 ≥ 24

Length ≥ 24/4

Length ≥ 6

Therefore, the length must be at most 6 feet.

If five squares, each with sides equal to 4n, are divided into 4 equal squares as shown, what will be of the sum of the perimete
vivado [14]
Side of a square = 4n

Side of the smaller square = 4n÷2 = 2n

Perimeter of one smaller square = 2n x 4 = 8n

Perimeter of 20 smaller squares = 8n x 20 = 160n

------------------------------------------------------------------------------
Answer: Perimeter of all the 20 smaller squares = 160n
