Sorry! OK. I'll make this quick. Formula: A= A+B+C+D
A= 134 cm2
B= 170 cm2
C= 202cm2
D= 238 cm2
So, just add them altogether.
A= 744 cm (But I don't know what the exponent would be. Sorry!) I think that is how it would be. Its been a while since of done Area, though. Sorry about not knowing the exponent. And sorry if this isn't acurate.
