Determine the area of squre ABCD with AB=3cm

Travka [436]

Answer:

Area: $9 cm^{2}$

Step-by-step explanation:

Since all sides of a square have equal lengths, the area of the square is $a^{2}$ (a = length of a side).

Since the length of the side of the square is given (is 3cm), the area of the square is $(3cm)^{2}$ = $9cm^{2}$

What is the area of triangle RST?

Paraphin [41]

Answer-

$\boxed{\boxed{\text{Area}_{RTS}=9\ unit^2}}$

Solution-

We know that,

$\text{Area}=\dfrac{1}{2}\times\text{Base}\times \text{Height}$

From the diagram,

RS is the base and UT is the height of the triangle.

Applying distance formula,

$RS=\sqrt{(3+3)^2+(2-2)^2}=\sqrt{(6)^2}=6$

$UT=\sqrt{(-1+1)^2+(2+1)^2}=\sqrt{(3)^2}=3$

Putting the values,

$\text{Area}_{RTS}=\dfrac{1}{2}\times6\times3=9\ unit^2$
