if a diagram shows a square with perimeter 40cm whats the percentage of the area inside the square that is shaded

5

Step-by-step explanation:

Eacl side of the square has a length of 5 cm.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
