### Question 12 :)

Hey everybody! Here is question 12 from our homework on page 93.

Use the Pythagorean Relationship to find the unknown area of each square:

a) Legs: 20cm2
32cm2
Hypotenuse: ?

In order to find the area of the square attached to the hypotenuse, we have to use the Pythagorean relationship. This means we have to find the sum of the area of the squares attached to the legs of the right triangle. (The hypotenuse is the diagonal line connecting the straight lines of the triangle, called legs).

20+32=52

The area of the square attached to the hypotenuse is 52cm2.

b) Legs: 100mm2
576mm2
Hypotenuse: ?

100+576=676

The area of the square attached to the hypotenuse is 676mm2.

c) Leg: 25cm2
hypotenuse: 90cm2
2nd leg: ?

90-25=65.

The area of the square attached to the 2nd leg is 65cm2.

d) Legs: 12cm2
12cm2
Hypotenuse: ?

12+12=24

The area of the square attached to the hypotenuse is 24cm2.

1. I really like how you told us how to use The Pythagorean Relationship. I also like how you wrote down the question and answered it in a different color. Well done!

2. Great use of colour
Well done
Awesome job:)
