Answer:

Option C is right

Step-by-step explanation:

The figure is a kite divided into 4 right triangles

Top two triangles are congruent and also bottom two triangles

Since top half angle is 45 we have height = base = 45 for top triangle

Top triangle right side area = 1/2 base x height = 1/2 (2.5)(2.5)

Area of two triangles at the top = 2.5 x 2.5 =6.25

Now bottom triangles each has base 6m and height same as 2.5 m

Hence area of two triangles at the bottom=2(1/2 )(6)(2.5)

=15

Together the total area of the figure = 6.25 +15 = 21.25 m^2

Option C is right.

Triangles ABC and DEF are similar. The perimeter of triangle ABC is 23. The perimeter of triangle DEF is twice as large as trian

allochka39001 [22]

Since ABC and DEF are similar, with ratio 1:2, it means that the sides of DEF are twice the size of ABC.

So, the perimeter of DEF is twice the perimeter of ABC, which means it is 46.

We can't pick any triplet of numbers that sum to 46 anyway, because in every triangle the sum of two sides must exceed the third one.

So, for example, the sides of DEF can't be 1, 5, 40, because 1+5 < 40.

A good option (although there are infinite possibility) could be for example 15, 11 and 20.
