Ted's patio is the shape of a right triangle. Tell how he should determine the area of the patio.

the answer should be 63. right?

b = base

h = height

A = 1/2 * bh

Yes. Then divide the product by 2.

Area of a triangle is equal to base times height

Sorry one half of that

I need to knoww

So do you mean that I should multiply the base (7) by the height (18)?
