Answer:
let the sides be 25x,12x and 5x ......then
25x+12x+5x=540
45x=540
x=25
sides are 25×12=300
12×12=144

1.x^2-8x-3=0
disctirminant =(-8)^2-4.1. (-3)
disctirminant =64+12
disctirminant =76
x1,2= -b(+,-)square root of disctirminant /2a
x1=-(-8)+square root of 76/2.1
x1=8+square root of 76/2
x2=8-square root of 76/2
Answer:
if the 'a base' is 6.5 & the height is 9 & 'b base' is 18.5, the answer is a = 112.5 cm^3
