Question

The work of a student to find the dimensions of a rectangle of area 6 + 8x and width 2 is shown below:

Step 1: 6 + 8x
Step 2: 2(4) + 2(6x)
Step 3: 2(4 + 6x)
Step 4: Dimensions of the rectangle are 2 and 4 + 6x

In which step did the student first make an error and what is the correct step?
Step 3; 2 + (4 + 6x)
Step 3; 2 + (4 ⋅ 6x)
Step 2; 2(4) + 2(4x)
Step 2; 2(3) + 2(4x)

Answer 1

Hello,
A=l×w
Step 1:
6+8x
Step 2:
2(3)+2(4x)
Step 3:
2(3+4x)
Step 4:
The dimension of the rectangle are 2 and 3+4x. As a result, Students makes the mistake at Step 2; 2(3) + 2(4x). Hope it help!

Answer 2

The dimension of a rectangle is 2(3) + 2(4 x)

what is the dimension  ?

A dimension is a measurement such as length, width, or height.

dimension of  a rectangle =  length (L) and width (W)

Given  : area of rectangle = 6 + 8 x  and width is 2

so ,

area of rectangle = length × width

 ⇒ (3+4 x) × 2

area of rectangle  = 2(3) + 2(4 x)

hence , students doing mistake in step 2 : 2(3) + 2(4 x)
