Perimeter..2times length plus 2 times width..
Answer: 108
Area..formula to find area of a parallelogram is base times height..
We don’t know the height
And since h is part of a dimension of a triangle..we can use this formula..a^2+b^2=c^2
225+b2=625
B^2=400
Square root of 400 is 20
So the height is 20
Hope it helped
