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

A. 2,956.5 square meters
B. 2,250 square meters
C. 3,309.75 square meters
D. 2,826 square meters
Answers
Answer:
A
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
