Question

What is the base of a triangle that has a height of 6 centimeters and an area of 18 centimeters? Use the formula h = StartFraction 2 A Over b EndFraction, where A represents the area of the triangle, h represents the height, and b represents the length of the base. One-third centimeter Two-thirds centimeters 3 Centimeters 6 Centimetersc

Answer 1

h = 6 cm

Explanation:

Atriangle = b×h/2

18cm² = 6cm×h/2

36cm² = 6cm×h

h = 36cm²/6cm

h = 6 cm

Answer 2

Base = 6 cm

Explanation:

Area of Triangle =
`(1)/(2) .{base}.{Height}`

Where A = 18 cm², h = 6 cm

Putting in the above formula

18 =
`(1)/(2)`(base)(6)

18 = 3(base)

base = 18/3

Base = 6 cm
