If two triangles have equal perimeters, then they could also have which of the following? Select all that apply.
Radda [10]

Answer: The answers is (B) equal areas.

Step-by-step explanation:  Given that two triangles have equal perimeters.

As shown in the attached figure, let us consider two right-angles triangles, ΔABC and ΔDEF, with sides AB = 3 cm, BC = 4 cm, AC = 5 cm, DE = 4 cm, EF = 3 cm and DF = 5 cm.

So the perimeters of both the triangles = 3 + 4 + 5 = 4 + 3 + 5 = 12 cm.

Since volume term is not valid in case of triangles, so they cannot have equal volumes. Therefore, option (A) is incorrect.

Area of ΔABC is

A_{ABC}=\dfrac{1}{2}\times AB \times BC = \dfrac{1}{2}\times 3\times 4=6~\textup{cm}^2,

and area of ΔDEF is

A_{DEF}=\dfrac{1}{2}\times DE\times EF=\dfrac{1}{2}\times 4\times 3=6~\textup{cm}^2.

Therefore, they may have equal areas and so option (B) is correct.

If the triangles have equal bases, then the heights will also be equal and both the triangles will be same. Similar is the case with equal heights. So, options (C) and (D) are incorrect.

Thus, the correct option is (B). equal areas.

*If diagonal of a square is of length 10√2 cm then the perimeter of square is ...............cm.*
Artyom0805 [142]

Answer: 1️⃣ 40

Step-by-step explanation:

<em>x - is the side of the square</em>

<em />x^{2} +x^{2}   =(10\sqrt{2})^{2}  \\2x^{2}}  =200\\2x^{2} \div  2=200 \div  2 \\x^{2} =100\\x=\sqrt{100} \\x=10 \:  [cm] - side \: of  \: a \: square<em />

<em>Find the perimeter of the square.</em>

<em>Perimeter of the square = 4 × 10 cm = 40 cm</em>

What is the interquartile range if the data set? 5,911,13,16,16,19,21
max2010maxim [7]

Answer:

Step-by-step explanation:

5,9,11,(13,16),16,19,21

the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5

Q1 = (9 + 11) / 2 = 20/2 = 10

Q3 = (16 + 19) / 2 = 35/2 = 17.5

interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==
