The perpendicular height of a right angled triangle is 70mm longer than the base .find the perimeter of the triangle if its area is 3000mm

Question

3000mm²

Answer 1

b represents the length of the base

b + 70 represents the height

 

3000 = (0.5)b(b + 70)  

 

Solve for b and b + 70, then us Pythagoras to determine c.

Then add b, b + 70, and c to determine perimeter
