Answer:
45750 cm²
Step-by-step explanation:
Area of triangle:
a = 4 and c = 5
base length = 3ac²
= 3 * 4 * 5 * 5
= 300 cm
height = 5 cm more than the base length
= 300 + 5
= 305 cm
[tex]\sf \boxed{\bf Area \ of \ triangle = \dfrac{1}{2}*base \ length * height}[/tex]
[tex]\sf =\dfrac{1}{2}*300*305\\\\= 150 * 305\\\\= 45750 \ cm^2[/tex]
