Question

If the area of triangle is 360 cm2 and the height is 18cm, find its base​

Answer 1

Formula for area of a triangle is 1/2 x base x height.

musing the information given you have:

360 = 1/2 x base x 18

First multiply both sides by 2:

720 = base x 18

Now divide both sides by 18:

Base = 720/18

Base = 40 cm

Answer 2

Solution:

Note that:

• Area of triangle = 1/2 x Base x Height
• Area of triangle = 360 cm²
• Height = 18 cm

Using the formula to find the area:

• 1/2 x Base x Height = Area of triangle
• => 1/2 x Base x 18 = 360 cm²
• => Base x 9 = 360 cm²
• => (Base x 9)/9 = 360/9 cm²
• => Base = 40 cm
