1 point

Your answer

x = 40

Step-by-step explanation:

Here is the complete question:

The area of the rectangle shown is 200 square units. Find the value of x. Width: 8 Length: 1/2x+5

The area of a rectangle is length multiplied by the width.

Area = Length × Width

Area = 200

Width = 8

Length = 200/8 = 25

Since length is 25 and it has bee denoted as 1/2x + 5. This will be:

1/2x + 5 = 25

1/2x = 25 - 5

1/2x = 20

x = 20 × 2

x = 40

Check:

= 1/2x + 5

= (1/2 × 40) + 5

= 20 + 5

= 25
