Watch

1 year ago

10) A windmill has four identical triangular sails made from wood. If each triangle

has sides of length 12 m, 15 m and 20 m, work out the total area of wood needed.

My answer is 360 but the book says it is 359. Why is it 359 ? Thank you!

The answer is 359 (rounded), so if youve got something else it would help to see what you did.
