Question

Please help me wit dis no one would help and i really need help

Answer 1

(4) 64 tiles,   (5) $\mathrm{N}=\mathrm{s}^{2}$,   (6)  $N^{2}=S^{4}$

Step-by-step explanation:

Given data: Side length of square tile = 1 ft

(4)  Side length of square pool = 8 ft

$\text {Number of tiles} =\frac{\text { Area of square pool }}{\text { area of square tile }}$

$=\frac{8 \times 8}{1 \times 1}$

= 64

Hence 64 tiles needed for the border.

(5) Suppose number of square tiles be N and side of square tub is s ft.

So, N = $\frac{s \times s}{1 \times 1}$

$\Rightarrow N=s^{2}$

So, the expression is $\mathrm{N}=\mathrm{s}^{2}$.

(6) The equivalent expression is $\mathrm{N}^{2}=\mathrm{S}^{4}$.
