Answer:
The lateral area = 450 mm²
Step-by-step explanation:
The lateral area of any prism is equal to the areas of the sides faces
∵ The base of the prism is triangle
∴ It has 3 side faces
∵ The lengths of the side faces are 5 , 12 , 13 and their height is 15
∴ The lateral area = (5 × 15) + (12 × 15) + (13 × 15)
= 75 + 180 + 195 = 450 mm²
The general form of an equation is

. Solving for (5+X)(5-X)=7 by multiplying the factors and subtratcting 7 on both sides gives the equation

, so
A = 1
B = 0
C = -18
