b = base
h = height
Area of triangle:
A = b ∙ h / 2
In this case:
b = 5 h , A = 160 in²
160 = 5 h ∙ h / 2
160 = 5 h² / 2
Multiply both sides by 2
320 = 5 h²
Divide both sides by 5
64 = h²
h = ± √64
h = ± 8
Height can not be negative so:
h = 8 in
b = 5 h
b = 5 ∙ 8 = 40 in
"The base of a triangle is five times its height. Its area is 160 square inches. Find the height and base, then enter their sum below."
Yall I'm so confused by this, if I could get some help that would be great!! Thank you!

Thank you! So you're saying that the sum is 40?
Not the sum is used for the area of a triangle, but half the product of two numbers.
The product of 5 and 8 is 40.
The product of 5 and 8 is 40.
How would I calculate the sum?
"sum" means you add
8+40 = 48
8+40 = 48
