Question

find the area of square of diagonals 12m. ​

Answer 1

Hey Mate..

${12}^{2} = {a}^{2} + {a}^{2} \\ 144 = 2 {a}^{2} \\ {a}^{2} = 72 \\ a = \sqrt{72}$

Then area=

${a}^{2}$

$= 72 \: m2$

Hope it helped ❤️❤️

$\bf \purple{ step \: by \: step \: explanation}$

Given:-

Diagonal of square = 12m

now ,

Diagonal of square ²= 2a²

→ 2a² = 12²

$\sf \implies {a}^{2} = \frac{144}{2} \\ \\ \sf \implies \: {a}^{2} = \frac{ \cancel{144} \: 72}{ \cancel{2}} \\ \\ \sf \implies \: {a}^{2} = 72 \\ \\ \sf \implies \: a = \sqrt{72}$

According to question .

→ we have to find the area of square .

Area of square = side²

→ (√72)²

→ 72 m²
