The length of a rectangular garden is 7 feet more than three times it width. the perimeter of the garden is 78 feet. find the length and width of the garden

The length of rectangular garden is 31 feet and width of rectangular garden is 8 feet

Given that perimeter of the garden is 78 feet

Also given that length of a rectangular garden is 7 feet more than three times it width

Let the length of rectangle be "L"

Let the width of rectangle be "W"

According to gven information,

length of a rectangular garden = 7 + 3(width of rectangle)

L = 7 + 3W

The perimeter of rectangle is given as:

perimeter of rectangle = 2(length + width)

78 feet = 2( 7 + 3W + W)

78 = 2(7 + 4W)

78 = 14 + 8W

78 - 14 = 8W

64 = 8W

W = 8

Thus width of rectangular garden = 8 feet

length of a rectangular garden = L = 7 + 3W

L = 7 + 3(8) = 7 + 24 = 31

Thus length of rectangular garden = 31 feet

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

tube or goog would be a great resource to with that question
