In rectangle abcd with side ad = 6 cm, point m is the midpoint of side
cd
and m∠amb= 90°. find the perimeter of the rectangle.

36

Step-by-step explanation:

the triangle that is formed by AMB is a 45 45 90 triangle, so meaning the legs are equal. so in can be concluded that AD = MD, since M is the midpoint of CD, then CD = 2AD

CD = 2(6) = 12 cm

so the perimeter is of the rectangle ABCD is

P = 2l + 2w

P = 2(6) + 2(12)

P = 12 + 24

P=36

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
