The ratio of the length of the rectangular field to its width 5: 2. the length of the field is 30yd. find the perimeter and area

Perimeter= 84

Area= 360

Step-by-step explanation:

We know that this field has portions split up by 7. The length is 5/7 of that, and the width is 2/7.

We know that the length is 30yd. 30/42 is the equivalent of 5/7. That means that 12/42 is the equivalent of 2/7.

Thus, the width of the field is equal to 12.

To find the perimeter we will add all sides. 30 + 30 + 12 + 12 = 84

We will multiply them to find area. 30 * 12 = 360

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
