The length of a rectangle is triple the width. If the area of the rectangle is 75 square inches, then find the length and width
1 answer:
Answer:
W = 5
L = 15
Step-by-step explanation:
Formula for Area of Rectangle is L × W
Since stated triple;
L = 3W
Area = L×W = 3W² = 75
It'll be:
3W² = 75
Divide both sides with 3:
<u>3</u><u>W</u><u>²</u> = <u>7</u><u>5</u>
3 3
W² = 25
Then square root both sides:
w = 5
Again stated that length is triple the width:
L = 5 × 3
L = 15
Therefore;
W = 5
L = 15

Step-by-step explanation:
Y= 70 x= 13i could be wrong but I hope this helped a little
here you gooo
you can just copy this
this is the exact squared root chart
X-2(-4)=2
X+8=2
-8. -8
X=-6. (-6,-4)
4-2y=2
-4. -4
-2y=-2
Divide both sides by-2
Y=1. (4,1)
1/4
