Area of kite is 1/2 times the two diagonals.
So, it would be 1/2 times 70 times 70.
Solve it and you get 2450.

The answer is 2450 square cm.
But the question is asking for meters so convert it.
1 cm is 0.01 in meters. 2450 times 0.01 equals 24.5 meters
24.5 square meters is your final answer.

Step-by-step explanation:

The sum of interior angles in a pentagon is 540°

100° + 145° + 120° + 80° + x = 540°

445° + x = 540°

x = 95°

Consider that the length of rectangle A is 10 cm and its width is 6 cm. Which rectangle is similar to rectangle A? A) A rectangl

HACTEHA [7]

ANSWER

B) A rectangle with a length of 15 cm and a width of 9 cm.

EXPLANATION

The given rectangle, A, has length, 10cm and its width is 6cm.

The rectangle that is similar to rectangle A, has the corresponding sides in the same proportion.

For option A, the triangle has length 9cm and width 6cm.

The ratio of the corresponding sides are:

$\frac{10}{9} \ne \frac{6}{6}$

Since the ratios are not equal, the two triangles are not similar.

For the triangle in option B, the length is 15cm and the width is 9cm.

The ratio of the corresponding sides are:

$\frac{10}{15} = \frac{6}{9} = \frac{2}{3}$

Since the sides of the triangle are in the same proportion, the two triangles are similar.

For option C, the proportions are not the same.

$\frac{10}{14} \ne \frac{6}{7}$

The proportions are not the same for the triangle in option D.

$\frac{10}{12} \ne \frac{6}{8}$
