What is the area of an isosceles trapezoid, if the lengths of its bases are 16 cm and 30 cm and the diagonals are perpendicular
kicyunya [14]

Call the point of intersection of the diagonals point X.

Each base is the hypotenuse of an isosceles right triangle whose sides are the diagonals and whose 90° angle is at X. The altitude of that triangle (⊥ distance to the base from X) is half the length of the hypotenuse. Then the height of the trapezoid is half the sum of the base lengths.

The area of the trapezoid is the product of the height and half the sum of the base lengths, hence is the square of half the sum of the base lengths.

... Area = ((16 cm +30 cm)/2)² = (23 cm)² = 529 cm²

What is the answer to 10 - 5 2/3 I suck at fractions
Free_Kalibri [48]
4 1/3 

Okay, I know fractions are scary, but we can do this alright?

First, you see the whole number on the side? Get that first.

10- 5 = 5

now we have 5 left and a scary fraction.  Don't panic, let's do this.  We know 1 is 3/3.  1 can be anything as long as the number on top and the number at the bottom are the same then it would be one.

So 3/3 is one then we can subtract:

3/3 -2/3 .

We subtract the top number and leave the one at the bottom the same.

3-2 = 1

Then we have 1/3.

As you took one away from the 5, it becomes a 4 and you put back the left over, 1/3.

Then you answer will be :

4  1/3
