Answer:
A= 3441
P = 260
Step-by-step explanation:
Area = l x w
93 x 37 = =3441
Perimeter = 2l + 2w
2(93) + 2(37) = 260

Answer:
9/50 or 0.18
Step-by-step explanation:
Complentary angles add to 90 degrees
a and b are complentary
a+b=90
a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7
m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37
angle a measures 53 degrees
angle b measures 37 degrees
