dusya [7]

Answer:

63.966

Step-by-step explanation:

Area of a kite is

\frac{pq}{2}

where p and q are the diagonals.

The horinzontial diagonal is 8.

We need to find the vertical diagonal length.

The top triangle diagonal measure is

{4}^{2}  +  {x}^{2}  =  {7}^{2}

16 +  {x}^{2}  = 49

{x}^{2}  = 33

x =  \sqrt{33}

The bottom triangle diagonal measure is

{4}^{2}  +  {x}^{2}  =  {11}^{2}

1 6 +  {x}^{2}  = 121

{x}^{2}  = 105

x =  \sqrt{105}

Add the two diagonals.

\sqrt{105}  +  \sqrt{33}

Substitute this in for the formula

\frac{8 \times ( \sqrt{105}  + \sqrt{33}  }{2}

Which simplified gu

A parking space is 20 feet long. A pickup truck is 6 yards long. How many inches longer is the parking space than the truck
masya89 [10]

1 yard = 3 feet.

Multiply the length of the truck by 3 to get total feet:

6 x 3 = 18 feet.

Subtract the length of the truck from the length of the parking space:

20 - 18 = 2 feet

1 foot = 12 inches.

Multiply 2 feet by 12:

2 x 12 = 24 inches longer.
