Question

what is area of a square if its diagonal is under root 3cm (_/3cm) long?

Answer 1

$\boxed{\boxed{\large\mathbf{1.5 \: cm^2}}}$
____________________________________

$\underline{\large\mathbf{Given :}}$

Diagonal of Square = $\mathsf{\sqrt 3 \: cm}$

$\underline{\large\mathbf{To \: Find :}}$

$\textsf{Area of Square}$

$\underline{\underline{\Large\mathfrak{Solution :}}}$

$\underline{\textsf{Using the Formula,}}$

$\boxed{\large\mathsf{\frac{1}{2} \: d^2}}$

$\underline\text{Putting the Value of d, We get}$

$\mathsf{=> \frac{1}{2} (\sqrt{3})^2}$

[ $\mathsf{\because \sqrt{3} \times \sqrt{3} = 3}$ ]

$\mathsf{=> \frac{1}{2} \times 3}$

$=> \boxed{\mathsf{ \frac{3}{2} = 1.5 cm^2}}$

Answer 2

Answer:

Square

Solve for area

A=4.5cm²

d Diagonal

3cm

Using the formulas

A=a2

d=2a

Solving forA

A=1

2d2=1

2·32=4.5cm²
