4. e. 30x30= 900mm
g. 50x50= 2500mm
f. 40x40= 1600mm
The area of e. is 900 square millimeters
The area of g. is 2500 square millimeters
The area of f. is 1600 square millimeters
9. a) 4x4=16 square cm.
2x2= 4 square cm.
3x3=9 square cm.
b) This is not a right triangle because 2 squared + 3squared doesn't equal 4 squared
12. a) a. squared + b. squared = c. squared
20 + 32 = 52 square cm.
b) a. squared + b. squared = c. squared
100 + 576 = 676 square mm.
c) c. squared - b squared = a. squared
90 - 25 = 65 square cm.
When the hypotenuse is there but one of the leg is missing, I figure it out that when you subtract the one of the legs to the hypotenuse, you will get the missing leg.
d) a. squared + b. squared = c. squared
12 + 12 = 24 square cm.
17. a) a. squared + b. squared = c. squared
21 squared + 28 squared = c .squared
441 + 784 = 1225 square cm.
b) a. squared + b. squared = c. squared
12 squared + 5 squared = c.squared
144 + 25 = 169 square cm.
