Answer:
B) 56cm^2
Explanation:
The area of the 2 triangles is
[2•((1+4+1)•2)]÷2
Solve that.
[2•((1+4+1)•2)]÷2
[2•((6)•2)]÷2
[2•(12)]÷2
[24]÷2
12
The area of the 2 triangles (together) is 12.
The area of the rectangle is 4•11=44.
The area of the whole thing is the rectangle plus the two triangles
44+12
That adds up to 56.
Put in the cm^2, and it's 56cm^2
56cm^2 is B
