we are given that
two triangles are similar
so, the ratio of their sides must be same
we get

now, we can solve for x
step-1: Cross multiply both sides

step-2: Simplify left side

step-3: Subtract both sides by 2x


step-4: Divide both sides by 4

so,
............Answer
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8
I believe the answer is $417.91
You cannot express 108/250 in a whole number but it can be simplified to 54/125
Slope = (y2 - y1) / (x2 - x1)
Let’s plug in our numbers, solve m, and then reduce
3 - (-3) / 1 - 3
6 / -2
Reduce > - 6/2
-3
Your slope is 3
