Formula for perimeter ;
P = length + length + width + width
P = 2l + 2w
l = -4 + 5w
l = 5w - 4
substitute into equation of perimeter
292 = 2(5w - 4) + 2w
292 = 10w - 8 + 2w
292 + 8 = 10w + 2w
300 = 12w
25 = w
substitute into eqution to find the length;
l = 5(25) - 4
l = 125 - 4
l = 121
therefore, the width is 25 and the length is 121
hope that helps, God bless!

The two little lines on the 2 sides of the triangle, mean that the two sides are the same.
When the two sides of a triangle are the same, the two lower inside angles are also the same,
Since the left side is given as 35 degrees, the right side, which is labeled as y is also 35 degrees.
