Answer 1

Answer:

$\huge\sf\purple{Answer}$

3. Find the side of the square whose perimeter is 40 cm.

• Perimeter = 40 cm

• side = ?

Perimeter of square = 4 × side .

➡️ 40 = 4 × side

➡️ side = 40/4

➡️ side = 10 cm

4. What is 888 minutes in hours and minutes.

• 1 hour = 60 minutes .

➡️ 888 / 60

➡️ 14 hours 40 minutes

5. If the area of square is 49 square cm then find its Perimeter.

• Area = 49 cm²

• Side = ?

• Perimeter = ?

Area of square = side²

➡️ 49 = side²

➡️ side = √49

➡️ side = 7 cm

Perimeter of square = 4 × side

➡️ 4 × 7 cm

➡️ 28 cm

6. If Finishing time is 10.15 P.M. and Time duration is 6 hours then find itsStarting time.

• finishing time = 10.15 pm

• duration = 6 hours

starting time = 4:15 am

7. What is the length of edge of cube of volume 1000 cubic cm.

• volume = 1000 cm³

• edge = ?

volume of cube = edge³

➡️ 1000 = edge³

➡️ edge = √1000

➡️ edge = 10 cm
