Question

Write the formula for the area a of a triangle.

a) A= 1/2 ×base×height
b) A= 1/3 ×base×height
c) A= 1/2 ×(base+height)
d) A=base×height

Answer 1

The formula for the area of a triangle is A = 1/2 × base × height. To find the area, multiply the base and height, and then divide the result by 2.

Step-by-step explanation:

The formula for the area of a triangle is given by the formula A = 1/2 × base × height. In this formula, the base and height of the triangle are multiplied together and then divided by 2.

Let's use this formula to find the area of the triangle with a base of 1.007 m and a height of 0.665 m:

1. Multiply the base and height: 1.007 m * 0.665 m = 0.669935 m².
2. Divide the result by 2: 0.669935 m² / 2 = 0.3349675 m².

The area of the triangle is approximately 0.335 m².
