Question

Can someone please help me with this problem???? A rectangle table is three times as it is wide. If the area is 75ft^2, find the length and width of the table??

Answer 1

From the information given you can get the following equations\[L=3W\]
\[L \times W=75\]

Answer 2

Sry,
L=3W
L*W=75

Answer 3

then just use substitution to solve for L and W

Answer 4

3W^2=75

Answer 5

so W^2 = 25 and W = 5

Answer 6

let length be 3x and width be x
l*w = 75
3x*x = 75
3x^2 = 75
x^2 = 75/3
x = root25
x = 5

so,
width = 5
length = 3(5)
= 15
