Answer 1

Question :-

find the area of a squre whose diagonal is 15m

Solution :-

Given :-

• Diagonal is 15cm.

Need to find :-

• Area of square

Using formula :-

${\boxed{\rm{\red{Area_{(Square )} = \frac{1}{2} d²}}}}$

Now, we put the value of diagonal and find the area.

$\sf:\longmapsto{Area_{(Square)} = \frac{1}{2} \times 15 {}^{2} } \: \: \: \\ \\ \sf:\longmapsto{Area_{(Square)} = \frac{1}{2} \times 225} \: \: \\ \\ \sf:\longmapsto{Area_{(Square)} = \frac{225}{2} } \: \: \: \: \: \: \: \: \\ \\ \bf:\longmapsto \red{Area_{(Square)} = 112.5}$

• Area = 112.5cm².
