2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.
<span>the answer
The triangle congruence says triangle ERT is congruent to triangle CTR. </span>
So first of all we need to know that area is length times width
Area = L x W
since we know the area is 42 and the length is 12 lets plug those in
42 = 12 x W
now we dont know what W is yet but we can figure it out by dividing 42 by 12
42/12 = 3.5
So W = 3.5!
but its asking for the perimeter and we know that perimeter is all of the sides of the rectangle added up. Heres a picture

3.5
see now we just add those all up together:)
12 + 12 + 3.5 + 3.5 = 31!!
so our perimeter is 31 inches:)
have a good one
