OpenStudy (anonymous):

4 x 4 = 16 ... 9 x10 = 90

OpenStudy (anonymous):

therefore it will be 4 * 13 + 9*6 = 52+54 = 106

OpenStudy (anonymous):

106 m²?

OpenStudy (anonymous):

Do you get it?

OpenStudy (anonymous):

No

OpenStudy (anonymous):

your method is right but you have to add the 90 with the 16, which becomes 106

OpenStudy (anonymous):

Oh, right you just add it. Right?

OpenStudy (anonymous):

yep, absolutely correct.
