3. Ting Group began work on a \7,000,000 contract in 2019 to construct an office building. During 2019, Ting Group incurred costs of \1,700,000, billed its customers for \1,200,000, and collected \960,000. At December 31, 2019, the estimated additional costs to complete the project total 3,300,000. Prepare Ting's 2019 journal entries using the percentage-of-completionmethod.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

my computer is slow i can not see it sorry

this cant be answered without the graph. you may need to add it.
