Answer:

C. 13

Step-by-step explanation:

from on online source, the question should be placed as thus:

Of the following integers, which is the closest approximation to (√2 + √5)^2 ?

A. 7

B. 10

C. 13

D. 15

E. 17

This is known as Algebraic expression. So we have to expand to simplify further

using  this identity  th (a+b)^2 = a^2 + b^2 +2ab

(√2 + √5)^2 =

(√2 + √5)(√2 + √5)

................Expansion of the above

\sqrt{2}* \sqrt{2} +\sqrt{2}* \sqrt{5} +\sqrt{2} *\sqrt{5}+\sqrt{5} *\sqrt{5}

2 + 5 + 2√10

~ 2 +5 + 2(3)

C. 13

In the diagram, the area of the given shape is 102 cm²

<h3>Area of a Kite </h3>

From the question question, we are to determine the area of the given shape

The given shape is a kite

The area of a kite is given by the formula,

A =\frac{pq}{2}

Where A is the area

p and q are the diagonals

In the given diagram,

p = 6cm + 6 cm = 12 cm

q = 3 cm + 14 cm = 17 cm

Thus,

Area of the kite = \frac{12 \times 17}{2}

Area of the kite = 6 × 17

Area of the kite = 102 cm²

Hence, the area of the given shape is 102 cm²
