I am not sure but I think the answer is of second one.
Answer:
B Is called legs
Step-by-step explanation:
<em>Congruent triangles</em> are two or more triangles with the same length of <u>sides</u> and measure of internal <u>angles</u>. Thus the <em>required</em> proof is as shown below:
From the given diagram, it can be <u>observed</u> that:
AB = AC (<em>similar</em> property of two lines)
AC = AE (<u>similar </u>property of two lines)
Also,
m<A is a <u>common</u> angle to ΔABC and ΔADE
So that it can be <em>concluded </em>that;
ΔABC ≅ ΔADE (Side-Angle-Side property)
Thus since ΔABC ≅ ΔADE are <u>congruent</u>, then;
BC = DE (<u>corresponding</u> sides of <em>congruent</em> triangles)

Given that in a square, length=width, let the length be L, the perimeter will be:
P=L+L+L+L=4L
but
4L=16x+24
thus the length of one side will be:
L=4x+6
hence the length of the perimeter is (4x+6) units and the width is (4x+6) units.
