Answer: 45

Step-by-step explanation:

As we can see here, the relation is as follows:

(1)(4)+1 = 4+1= 5

(2)(5)+2 = 10+2 =12

(3)(6)+3 = 18+3= 21

Then, if we follow the same pattern:

(4)(7)+4 = 28+4= 32

Hence:

(5)(8)+5 = 40+5=45

A rectangle has a length of 14 yards less than 9 times its width. If the area of the rectangle is 6183 square yards, find the le

Jlenok [28]

Answer:

$l=238\ yards$

Step-by-step explanation:

From the question we are told that:

Area of Rectangle A=6183

Equation of Length

$l=9w-14$

Where

$w=width\ of\ triangle$

Generally the equation for Area of Rectangle is mathematically given by

$A=(9w-14)w$

$A=9w^2-14w$

$6183=9w^2-14w$

$9w^2-14w-6183=0$

$w=28$

Therefore

$l=9(28)-14$

$l=238\ yards$
