Question 757511: rectangle 15cm wide having perimeter of 64cm is cut into 2 right angled triangle along the diagonal what is the area of each triangle? Answer by Cromlix(4381) (Show Source):
You can put this solution on YOUR website! 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.
