An equilateral triangle with side length 20 cm is shown in the diagram, work out the area of the triangle. Give your answer rounded to 1 DP.

173.2 cm²

Step-by-step explanation:

Use the equilateral triangle area formula, A = a²

Plug in the side length and solve:

A = a²

A = (20)²

A = (400)

A = 173.2

So, the area of the triangle is approximately 173.2 cm²

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
