Question

What is the length of the base of a right triangle with an area of 20 m² and a height of 4 m? A.5 m B.10 m C.80 m D.160 m

Answer 1

to find the length, follow the equation l(w) = a

l or b = length or base
w or h = width or height
a = area

b x h = a
b x (4) = 20
4b = 20
4b/.4 = 20/4
b = 20/4
b = 5

A. 5m is your answer

hope this helps
