Answer:
The dimensions are 94x28
The length is 94 and the width is 28
Step-by-step explanation:
The Rectangle Perimeter Formula is P=2(l+w)
We know the formula for the length is l=10+3w
Where w is the width
We can insert the formula for the length into the rectabular perimeter formula.
244=2(10+3w+w)
244=2(10+4w)
244=20+8w
Subract 20
224 = 8w
Divide by 8 to get w
28 = w
Now that we have the width we can insert it into the length formual to find the length
l = 10+(3)28
l = 10+ 84
l = 94
Based on these calculations the dimensions are 94x28. To prove it we put both values into the Rectangular Perimeter formula.
P = 2 (94+28)
P = 2(122)
p = 244
The answers match therefore it is correct.
