If the garden were in the shape of a square, all of its sides would be of equal length. so if you divide 240 by 4 sides, each one would be 60 feet. Then, to find the square garden's area, you multiply 60 x 60 = 360 feet².
If the garden was 50 by 70, you would multiply the two values together to find the area, which is 350 feet².
Because 360 > 350 , Tyler's design would yield the maximum area for a garden
Hope this helps :)
