Question

The diagram shows a square. Find the length of the side of the square.

Answer 1

Answer:

20 centimeters

Step-by-step explanation:

A square has all sides equal.

6x - 1 = 4x + 6

6x - 4x = 6 + 1

2x = 7

x = 7/2

Plug in x as 7/2 in one of the side lengths.

6(7/2) - 1

42/2 - 1

21 - 1 = 20

Answer 2

Answer:

20

Step-by-step explanation:

Sides of a square are always equal.

6x - 1 = 4x + 6

Move the variable to L.H.S and change its sign

6x - 4x - 1 = 6

Move the constant to RHS and change its sign.

6x - 4x = 6 + 1

Simplify

2x = 7

Divide both sides by 2

2x/2 = 7/2

X = 7/2

Again,

6x - 1

plugging the value of X

= 6 * 7/2 - 1

= 3 * 7 - 1

= 21 - 1

= 20

Hope this helps...
