What is the length of the base of a right triangle with an area of 20m2 and the height of 4 m

The base is 10 meters

Step-by-step explanation:

The area of a right triangle is (b * h) : 2 = a

Let's input the given values and find the value of b:

(b * 4) : 2 = 20

4b : 2 = 20

2b = 20

b = 10

Check:

(10 * 4) : 2 = 20

40 : 2 = 20

20 = 20

It works!
