Use the information to write the dimensions of each rectangle in terms of w, the width of the 1st one.

1st rectangle;
l = 2w
w = 2

2nd rectangle:
w = w 
l = 2w + 4

If the area of the 2nd rectangle is 70 square meters, you will use the area formula to write an equation that you will solve using the factoring.

A = lw
70 = w(2w + 4)
70 = 2w^2 + 4w
0 = 2w^2 + 4w -70
0 = 2 (w^2 +2w - 35)
0 = 2 (w + 7) (w - 5)

To get zero, the width would need to be -7 or 5.  Because it is a distance, it has to be 5 meters.

The width of both rectangles is 5 meters.

A warehouse charges its customers $4 per day for every 10 cubic feet of space used for storage. The figure records the storage u
ikadub [295]

Figure 1 is the original figure, while figure 2 is modified, so that a triangle and a rectangle can be easily observed.

The area of triangle and rectangle represents the total number of cubic feet of storage multiply by the number of days of storage usage.

Hence

Total Area = Area of triangle + Area of rectangle

= 30 x 10,000 + ½ 30 x (30,000 – 10,000)

= 300,000 + 300,000

= 600,000

As 10 cubic feet of storage cost $5 for a day, so total amount company have to pay

<span>= (5 x 600,000) / 10 = $300,000</span>
