Please help me with the question please ASAP

Answer:

The ratio of perimeter of ABCD to perimeter of WXYZ = \frac{2}{3}

Step-by-step explanation:

First, we have to determine the multiplicative factor of the dimensions for both figures.

Considering sides AB and WX,

multiplicative factor = \frac{12}{8}

                                = 1.5

So that:

XY = 6 x 1.5 = 9

YZ = 7 x 1.5 = 10.5

ZW = 7 x 1.5 = 10.5

Perimeter of ABCD = 6 + 7 + 7 + 8

                                = 28

Perimeter of WXYZ = 9 + 10.5 + 10.5 + 12

                                 = 42

The ratio of the perimeters of the two quadrilaterals can be determined as;

ratio = \frac{perimeter of ABCD}{Perirmeter of WXYZ}

       = \frac{28}{42}

       = \frac{2}{3}

The ratio of the perimeter of ABCD to perimeter of WXYZ is \frac{2}{3}.

Aleks [24]
Answer
Length: 12 feet Width:4
Explanation
To get the area of a rectangle you times the length by the width
It says the length of the wall is 4 feet longer than TWICE it’s width since 12 times 4 is 48 and 12 is twice the amount of 4 plus 4 feet it fits the requirements of this question
