Answer:
- Length = 28 meters
- Width = 4 meters
Step-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters
Answer:
B.
Step-by-step explanation:
First in order to solve this problem we need to simplify the answer choices.
A. 6×8 + 6×6 = 48+ 36
B. 12×4 + 12×1=48+12
C. 4×44 + 4×3=176+12
D. 8×6 + 8×4 = 48+32
As you can see there is one expression that is equivalent to 48+12. Answer choice B is correct.
Answer:
.03397
Step-by-step explanation:
The fifth decimal is 7, and the number after that is 4. Because 4 is not greater than or equal to 5, we do not round up the 7.
3 and 1/8 times 3 and 1/4=25/8 times 13/4=325/32=10 and 5/32
3 and 1/8 and 3 and 1/4
