If a square has the area of 392.04 metre squared then what is its perimeter

you say 392.04 multiply by 4 sides which are 2 lengths and 2 width

79.2 meters

Step-by-step explanation:

since the shape is a square, the area is given by (side length)^2

so to find the side length, which will be the same for all 4 sides, take the square root of the area.

sqrt(392.04) = 19.8 meters

the perimeter is the sum of all the sides, which is 19.8 x 4 = 79.2.

hope this helped!

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.
