Answer:
perimeter = 107.4 m
area = 640.82 m²
Step-by-step explanation:
The line connecting the the centers of the adjacent sides of the garden is 20 m long. The line is a diagonal that forms an hypotenuse sides of a triangle.
The length of side of the rectangle has a ratio of 1 : 2. This means one side has a length a meters and the other 2a meters.
Pythagoras theorem can be use to get a since a right angle is formed due to the diagonal.
(a/2)² + (2a/2)² = 20²
(a/2)² + (a)² = 20²
a²/4 + a² = 400
(a² + 4a²)/4 = 400
5a²/4 = 400
cross multiply
5a² = 1600
a² = 1600/5
a² = 320
square root both sides
a = √320
a = 17.88854382
a ≈ 17.90
The required length is a = 17.90 m and the other side will be 17.90 × 2 = 35.80 m.
Area = length × breadth
area = 17.90 × 35.80 = 640.82 m²
perimeter = 2(l + b)
perimeter = 2(35.80 + 17.90)
perimeter = 2(53.7)
perimeter = 107.4 m
Answer:
d=-8.9
Step-by-step explanation:
Isolate the d variable.
-9.39 - 3.4d = -1.1d + 11.08
-9.39 -2.3d= 11.08
-2.3d= 20.47
d=-8.9
Answer:
the answer is A 4140
Step-by-step explanation:
multiply 12,000 ans 6.9 as a decimal so it would be 12,000*0.69 then you multiply your answer 8280 with the time which is 5 and you get your answer i think not sure
Answer:
The surface area of a rectangular prism with length of
17, a width of 5 and a height of 8 is:
522.0000 square units.
Step-by-step explanation:
Surface Area =
[(Length x Width) + (Length x Height) + (Width x Height)] x 2
I hope this helps!!! have a wonderful day :)
