Answer:
Length of mat = 4 inches
Width of mat = 12 inches
Area of table mat = 48 square inches
Step-by-step explanation:
Given
Perimeter = P = 32
Let l be the length of the table mat and w be the width of table mat
According to given statement

The perimeter of a rectangular object is given by:

Putting w=3l and value of P

Dividing both sides by 8

So
Length = l = 4 inches
And
Width = 3l = 3*4 = 12
Now

Hence,
Length of mat = 4 inches
Width of mat = 12 inches
Area of table mat = 48 square inches
Your answer should be B.
x+2y=8
Answer:
5 35/72 kilometers
Step-by-step explanation:
The distance around a lake is 6 7/12 kilometers. Evan rode his bike 5/6 of the distance around the lake. What is the distance in kilometers that Evan rode
This is calculated as:
Total distance = 6 7/12 km
Evan rode = 5/6 of the distance
Hence:
The distance Evans rode is
5/6 of 6 7/12
= 5/6 × 79/12
= 395/72
= 5 35/72 km(kilometers)
