Square

Square JKLM has sides of length 24 cm. Point S is the center of LM. Calculate the area of the quadrant JKSM in cm².

Correct answer:

S =  432 cm²

Step-by-step explanation:

$$\begin{gathered} a=24\text{ cm } \\ {S}_1=a^2=24^2=576{\text{cm}}^2 \\ {S}_2=a\cdot (a\mathrm{/}2)\mathrm{/}2=24\cdot (24\mathrm{/}2)\mathrm{/}2=144{\text{cm}}^2 \\ S=S_1-S_2=576-144=432{\text{cm}}^2 \end{gathered}$$
