Question

The triangle shown below has an area of 5 units. Find x

Answer 1

x=2

Explanation:

Area of triangle = 1/2 base * Height

height = 5

let base be x

hence

5=
`(1)/(2) x` * 5

5 =
`(5)/(2) x` multiply both sides by 2

10 = 5x

x = 10 /5 = 2

x= 2

Answer 2

The length of x is 2 units

Explanation:

First of all we have to know the formula to calculate the area of ​​a triangle:

a = area = 5u²

h = heigth = 5u

b = base

a = (b * h) / 2

we replace with the known values

5u² = (b * 5u) / 2

5u² * 2 = b * 5u

10u² / 5u = b

2u = b

The length of x is 2 units
