The width of a triangle of 7 feet longer than its length. Find the dimensions of the rectangle such that the perimeter of the re
AveGali [126]

Answer:

Length = 37 feets

Width = 44 feets

Step-by-step explanation:

Given that :

Length = l

Width, w = 7 + l

Perimeter , P of rectangle = 162

Recall:

Perimeter of a rectangle = 2(l + w)

P = 2(l + w)

162 = 2(l + (7 + l))

162 = 2(l + 7 + l)

162 = 2(7 + 2l)

162 = 14 + 4l

162 - 14 = 4l

148 = 4l

l = 148 / 4

l = 37 feets

Width = l + 7

Hence,

Width = 37 + 7 = 44 feets

Could someone help I’m so confused
oksano4ka [1.4K]

Answer:

6/4

Step-by-step explanation:

ratio of x to y is the slope so

you can use butterfly method/cross multiply (multiply numerator on one side to the denominator on the other to bring all the terms up and then solve for y)

4(y+3)=6(x+2)

4y+12=6x+12

y=6/4x

so it would be 6/4
