Question 757511
Perimeter of a rectangle = 2 * length +
2 * width.
64 = 2x + 30
2x = 64 - 30
2x = 34
x = 17
Length = 17cms
Therefore Area = length * width
               = 17cms * 15cms
               = 255 cm^2
If the rectangle is divided into 2
Each triangle would have an area
of 255/2 = 127.5 cm^2
Hope this helps.
