Question 8

Write the correct answer from the given four options.

A square board has an area of 144 sq units. How long is each side of the board?

a) 11 units
b) 12 units
c) 13 units
d) 14 units

Answer 1

Given, area of square board = 144 sq units
$\therefore$ $(\text{Side}{)}^2=144$ [$\because$ area of square $=(\text{side}{)}^2$]
$\Rightarrow (\text{Side}{)}^2=(12{)}^2$ [Square of $12$ is $144.$]
$\Rightarrow$ Side = 12 units
Hence, the length of each side of the board is 12 units.
