Just help me with the error analysis, please I really need it.

SA=744

Step-by-step explanation:

Surface area mean the sum off every single area of the shape

so we have here two rectangle area= 14*13*2=364

and one  rectangle are in the bottom= 14*10=140 cm

and two triangle are= 10*12*2=240 cm

so the some of them is SA=364+140+240=744

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
