Mathematics
1 answer:
Montano1993 [528]3 years ago
5 0

Answer:

80 cm

Step-by-step explanation:

The diagonals divide the rhombus into four congruent triangles.  The height of each triangle is 18/2 = 9, and the hypotenuse is 41.  Using Pythagorean theorem, the width of each triangle is:

c² = a² + b²

41² = 9² + x²

x = 40

Therefore, the longer diagonal is 2×40 = 80.

A rectangular garden measures by 30ft and 40ft. Surrounding (and bordering) the garden is a path 3ft wide. Find the area of this
Nookie1986 [14]

Answer:

312 ft²

Step-by-step explanation:

<u>Area of the garden = Length x Width</u>

Area of the garden = 30 x 40 = 1200ft²

<u>Length of the garden and path = Length of the garden + 3 ft on both sides</u>

Length of the garden and path = 30 + 3 + 3 = 36 ft

<u>Width of the garden and path = Width of the garden + 2 ft on both side</u>

Width of the garden and path = 40 + 3 + 3 = 46 ft

<u>Area of the garden and path = Length x Width</u>

Area of the garden and path = 36 x 46 = 1512 ft²

<u>Area of the path = Area of the garden and path - Area of the garden</u>

Area of the path = 1512 - 1200 = 312 ft²

Answer: 312 ft²

blagie [28]

Answer:

B) 2.849

Step-by-step explanation:

Given: 2.85 which is rounded to the nearest hundredth place.
