The length of one base of a trapezoid is 19 less than five times the length of the other base. if the trapezoid has a height of 18 feet and an area of 477 ft squared, find the length of the longer base

The length of longer base is 41 feet

Solution:

The area of trapezoid is given as:

Where , "a" and "b" is the length of base and "h" is the height

The length of one base of a trapezoid is 19 less than five times the length of the other base

a = 19 less than fives times b

a = 5b - 19

Height of 18 feet and an area of 477 ft squared

h = 18 feet

area = 477 square feet

Substitute the values in above formula

Therefore,

a = 5b - 19 = 5(12) - 19 = 41

Thus length of longer base is 41 feet

your answer is a

$320 to $405

step by step explanation:

in one day he earns between $64 and $81

therefore if he works for 5 days, he will earn between 64 x 5 to 81 x 5

= $320 to $405
