62.4 + 108.6 = 171

171*2=(170+1)*2=340+2=342

The perimeter of a figure is defined by length of its 2D shape.

For a rectangle it is the sum of the length of all its sides

P = a1 + a2 +b1 + b2

Since a rectangle has two sides with the same lengths as the other two

a1 = a2 ; b1 = b2

P = 2(a1 + b2)

Three times a number is three more than twice the number. Which equation can be used to find the value of x, the unknown number?

Misha Larkins [42]

We have to find the equation for three times a number is three more than twice the number.

Let the number is x.

Three times a number = 3x

Three more than twice the number. = 3+2x

These two equations should be equal.

Hence, we have

$3x=3+2x$

Therefore, the equation 3x = 3 + 2x can be used to find the unknown x.

A is the correct option.
