Answer:
Step-by-step explanation:
1. The result should by a 2 digit number.
So, I fix a two digit number first, say 60.
Then, I multiplied it by some random integer, say 4 and got 240.
Now, 240 is my dividend and 4 is my divisor.
My division problem is:
2. The result should be a 3 digit number.
So, I fix a three digit number first, say 600.
Then, I multiplied it by some random integer, say 3 and got 1800.
Now, 1800 is my dividend and 3 is my divisor.
My division problem is:

1+1 is equal to 3-1. 1+1=2. 3-1=2. 2=2
Answer:
Area = 23.12 cm²
perimeter = 24.28 cm
Step-by-step explanation:
top shaded region is circular arc with 90° sector angle
so perimeter of arc is 90 / 360 * 2πr
here radius of arc is half the length of square side
r = 6.8/2 = 3.4
top area shaded perimeter = 90/360 * 2 * 3.14 * 3.4
= 1/4 * 2 * 3.14 * 3.4
= 5.338
bottom region perimeter is also same
total perimeter of shaded region is = side + side + two arcs
= 6.8 + 6.8 + 2 * 5.338
= 13.6 + 10.676
= 24.276
= 24.28
Area of top shaded region is 90/360 * πr²
A = 1/4 * 3.14 * 3.4²
= 9.0746
bottom shaded region area is half of area of square - area of bottom arc
= 6.8 * 3.4 - 9.0746
= 23.12 - 9.0746
= 14.0454
so total area of shaded region is 9.0746 + 14.0454
= 23.12
or you can just calculate area as half of area of total square = 6.8² / 2
= 23.12
