Find the height of a triangle whose base is 50 cm and whose area
is 500 cm².

height = 20 cm

Step-by-step explanation:

The area (A) of a triangle is calculated using the formula

A = bh ( b is the base and h the perpendicular height )

here b = 50 and A = 500, hence

× 50h = 500, that is

25h = 500 ( divide both sides by 25 )

h = 20 cm

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

not sure but it may be b, as i said i'm not sure.
