Given AB
≅
DC and
m∠C
=72, find
m∠A

72

Step-by-step explanation:

angle A =72

Step-by-step explanation:

since AB = DC

then angle C = angle A

72 = <A

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
