Can you guys ? also explain step by step. (letter b is 34cm squared)

C

Step-by-step explanation:

The area of the two triangle on the top:

area of a triangle=1/2bh

1/2(1)(4)

=2

I found the bace because the height of thecenter sqare is 5 and there are congruent triangle on the end so 7-5/2=1

Next, we multiply 2 by four because there are four triangle altogether on each end.

2x4=8

Next, the formula for the area of the center square is bh, which is 2x5=10

Finally, the two outside squares' areas would equal 40 altogether because 5x4=20x2=40cm^2

10cm^2+8cm^2+40cm^2=58cm^2

so, the answer is C

HOPE THIS HELPS!!!
