3. When calculating the area of a rectangle or square, what formula do you insert into the worksheet? O=[+W O=L/W O= L-W O=L*w

we use to calculate the area of a rectangle or Square => ( Length * Width ) ...

Formula to find the area of a rectangle is area = length * width.

To use the formula , All you need to know is the measurements of the sides of a rectangle. We pick one side as the length , And the other side next to it is the width.

• The area of a square can be calculated using a2 where a is the length of its side...

RectangleArea = l × w

l = length w = width

SquareArea = a2

a = sides of square

1st Attachment shows the formula of Rectangle...

2nd attatched shows the formula of square ...

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
