Answer: r+7
Whatever his age is now, we add 7 to it. So we simply add 7 to r getting r+7.
Example: Say he is 10 years old now
r = 10
r+7 = 10+7 = 17
meaning he will be 17 seven years from now
Answer:
the total area is 15.6 square units
Step-by-step explanation:
hello,
you can find the total area dividing the shape into two known shapes
total area= area of the trapezoid +area of the semicircle
then
step one
find the area of the isosceles trapezoid using

where
a is the smaller base
b is the bigger base
h is theheight
A is the area
let
a=2
b=5
h=4
put the values into the equation

Step two
find the area of the semicircle
the area of a circle is given by

but, we need the area of half circle, we need divide this by 2

now the diameter of the semicircle is 2, put this value into the equation

find the total area
total area= area of the trapezoid +area of the semicircle

so, the total area is 15.6 square units
Have a good day.
