Using the formula for the perimeter and area of rectangle, the dimensions are: Length = 19 m; width = 9 m.
<h3>What is the Perimeter and Area of a Rectangular Shape?</h3>
Perimeter = 2(length + width)
Area = (length)(width).
Let x represent the length and y the width, therefore:
2(x + y) = 56 --> eqn. 1
xy = 171 --> eqn. 2
Rewrote eqn. 1
x + y = 56/2
x = 28 - y
Substitute x = (28 - y) into eqn. 2
171 = (28 - y)y
171 = 28y - y²
171 - 28y + y² = 0
y² - 28y + 171 = 0
Factorize
(y - 9)(y - 19)
y = 9 and y = 19
Therefore, the dimensions are: Length = 19 m; width = 9 m.

the answer is D
Step-by-step explanation:
Hope this helped
Answer:
just keep in mind am not sure if the answer 6:15:20
Step-by-step explanation:
now we have ab= 2 : 5
and bc= 3 : 4
so b is the common one between them so multiply both of the b together which will give u 15 so now we have b = 15
to get a multiply 2 by 3 to get 6 so a = 6
to get c multiply 4 by 5 to get 20 so c = 20
now I hope that its correct and that u understood
Answer:
Step-by-step explanation:
1/4 x 2 = 2/4
2/4 simplified = 1/2
