Answer:
Area=2232 square ft
Perimeter=206 ft
Step-by-step explanation:
given
the diagram is a rectangle
length=72 ft
width=31 ft
we know that
formula of the area of rectangle= length × width
Area=72×31 square ft
Area=2232 square ft
Now calculate the perimeter
perimeter of rectangle=2(length+width)
perimeter=2(72+31)
perimeter=2(103)
perimeter=206 ft

Answer:
Mikhail is 5 years old
Step-by-step explanation:
Represent each member with a variable.
X= Gabrille
Y=Mikhail
X+Y=20 (sum of their ages is 20)
X=3y (Gabrille is 3 times Mikhails age)
Substitute 3Y into the first equation (simultaneous equation)
. 3y+y=20
. 4y=20 (divide both sides by 4)
y=5
To check your answer.
X+5=20
X=20-5
X=15
15 is 5 times 3.
