Question

1. a square board has sides 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 the given side - length

Here, $s = 1.401$ m. So, $A=(1.401)^2$.
Calculating $(1.401)^2=1.401\times1.401 = 1.962801$ $m^{2}$.

Answer:

$1.962801$ $m^{2}$
