Answer:

Step-by-step explanation:
First you need to break the shape up to rectangles to make it easier to solve.
bottom rectangle : 15 x 3 = 45m^2
Top rectangle : 12 x 3=36m^2
Middle rectangle : 12-3-3=6 (because we already solved the top and bottom part of it)
we need to work out the base so we do 15-5= 5cm
6 x 5 = 30m^2
add them all together
30+36+45=111m^2
Answer:
Lindsey owns 12 books
Step-by-step explanation:
1/3x:Lindsay
x:Destiny
1/4x: Henry
1/3x+1/4x+x=57
4/12x+3/12x+x=57
7/12x+x=57
19/12x=57
x=57*12/19
x=36
1/3x=36/3
1/3x=12
