Question

a square board has side 1.407m long. using mathematical tables, find the area of the board.

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $s$ is the side - length of the square.

Step2: Substitute given side - length

Given $s = 1.407$ m, then $A=(1.407)^2$.
$A = 1.407\times1.407=1.979649$ $m^{2}$

Answer:

$1.979649$ $m^{2}$
