Question

recall that the perimeter of a figure such as the one to the right is the sum of the length of its sides. find the perimeter of the figure. the figure (a red t - shaped figure) has side lengths: 18x, 28, 40, 4x, 6x, 60, 48, 8x

Explanation:

Step1: List all side lengths

$28, 18x, 40, 6x, 48, 8x, 60, 4x$

Step2: Group like terms

$(28 + 40 + 48 + 60) + (18x + 6x + 8x + 4x)$

Step3: Calculate constant sum

$28+40+48+60 = 176$

Step4: Calculate variable sum

$18x+6x+8x+4x = 36x$

Step5: Combine results

$176 + 36x$

Answer:

$36x + 176$
