Question

Perimeter of a square plot with side 2$x$ is 40 units. Find the length of the side of the square plot.

• A. 5 units
• B. 16 units
• C. 10 units
• D. 20 units

Answer 1

The correct option is C

10 units

Perimeter of square = 40 units
$4\times$ side = 40
$4\times 2x$ = 40
$8x$ = 40

So, $x$ = 5 units.

So, the length of each side is $5\times 2$ = 10 units.
