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
