Question

If the base of a triangle is 20mm and the area of the triangle is 40m2. then what will be the height and how can we find it​

Answer 1

Use the formula for area of a triangle:

Area = 1/2 x base x height.

Fill in what you know:

40 = 1/2 x 20 x height

Multiply both sides by 2:

80 = 20 x height

Divide both sides by 20

Height = 4 m

Answer 2

Answer: 4 mm

Step-by-step explanation: this is because if you double the area then you will get the Area of 80 and if you divide it by 20 you will get 4 mm
