Step-by-Step Solution

A

= side × side =

24 \times 24 = 576 cm^{2}

. The trap is

96 cm^{2}

: that is

4 \times 24

, which gives the PERIMETER of the tile, not the area — and a perimeter would not even be measured in

cm^{2} .48 cm^{2}

2 \times 24

and

288 cm^{2}

is half of the correct answer.

Answer: D)

576 cm^{2}

Area measures how much flat space a shape covers. The unit is a **square** of side 1 — so

cm^{2}

(square centimetres),

m^{2}

(square metres), etc. To measure the area of a rectangle visually, imagine covering it with 1-cm squares: count them. A rectangle 5 cm by 3 cm holds

5 \times 3 = 15

little squares, so its area is

15 cm^{2}

. The general formula is the same idea: area of rectangle =

l \times b
