The formula of a perimeter of a rectangle:
We have:
Substitute
<h3>Answer: Length = 35 in, Width = 25 in.</h3>
Answer:
The closet equivalent of the ratio of 'a' to 'c' is:
Step-by-step explanation:
Given
i.e.
a=0.63x
i.e.
c=3/8x
Hence,
Thus, the closet equivalent of the ratio of 'a' to 'c' is:
Answer:
Step-by-step explanation:
The length of a rectangle is three times the width. Find the width if the perimeter is 80 cm.
PERIMETER = 2L +2W
L=3W
PERIMETER= 2(3W) +2W
80= 6W +2W =8W
80=8W
W=10
L=3X10=30
CHECK]
(2x10) + (2X30) =20+60=80
x
Answer:
The larger number is 40, and the smaller one is 23.
Step-by-step explanation:
Let x be the larger number.
Let x - 17 be the smaller number.
x + (x - 17) = 63
2x - 17 = 63
2x = 80
x = 40
Hence, the smaller number is 40 - 17 = 23.
Hope this helped!
