Length of CA = 6x - 30

Length of AT = 2x + 30

We know that all sides of a rhombus are congruent.

Which means :


= 6x - 30 = 2x + 30


= 6x - 30 - 2x = 30


= 4x - 30 = 30


= 4x = 30 + 30


= 4x = 60


= x = (60)/(4)


= x = 15

Thus, the value of x = 15

Then :

Measure of CA :


= 6x - 30


= 6 * 15 - 30


= 90 - 30


= 60

Thus, measure of CA = 60

Measure of AT :


= 2x + 30


= 2 * 15 + 30


= 30 + 30


= 60

Thus, measure of AT = 60

Perimefer of rhombus CAT :


= 4 * side


= 4 * 60


= \color{plum}240

Therefore, the perimeter of rhombus CAT = 240
