Answer:

64 times 7

Step-by-step explanation:

A rectangle has a length that is 9 inches less than twice its width. The area of the rectangle is 180 square inches.
a. Write an equation that represents the situation.
b. Find the length and width of the rectangle.
c. Find the perimeter of the rectangle.
pls help lols

Answers

Answer:

Step-by-step explanation:

a) Let the width = w

Two times its width = 2*w = 2w

9 inches less than 2w = 2w - 9

Length = 2w - 9

Area of rectangle = length *width = 180 square inches

(2w - 9 ) * w = 180

2w*w - 9*w = 180

2w² - 9w - 180 = 0

b) sum = -9

Product= -360

Factors = -24 , 15 {15 *[-24] = -360 and 15 + (-24) = -9 }

2w² - 9w - 180 = 0

2w² - 24w + 15w - 180 = 0

2w(w - 12w) + 15(w - 12) = 0

(w -12) (2w + 15) = 0

{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}

w - 12 = 0

w = 12 inches

l = 2w -9

= 2*12 - 9

= 24 - 9

l = 15

length = 15 inches

Width = 12 inches

c) Perimeter = 2 *(length + width)

= 2*(15 + 12)

= 2 * 27

= 54 inches

B. 2,250 square meters
C. 3,309.75 square meters
D. 2,826 square meters

Answers

Answer:

Step-by-step explanation:

πr^2

π * 15^2 = 706.858347

75 X 30 = 2250

706.858347 + 2250 = 2956.858347

The total area enclosed by the track is 2956.5 square meters

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

The given figure has one rectangle and two semicircles

The area of rectangle is length times width

Area = length × width

=75×30

=2250 square metres

Area of circle is πr²/2

=3.14×15²/2

=706.5/2

=353.25

As there are two semicircles = 2×353.25

=706.5

Total area is 2250+706.5 which is 2956.5 square meters

Hence, the total area enclosed by the track is 2956.5 square meters
