What is the area of the rectangle?   60 units² 66 units² 70 units² 74 units²

Thanks for the pic. I calculated the sides using pythagorean formula. I counted the boxes and found the a's and b'so. Came up with short side being √37 and the larger side √148.
A=lw
A=√37 x √148
A=√5476
A=74 units ^2

You actually get 2 solutions but area is positive.

Why are u not just putting the numbers this is to much
