Question

If you answer correctly then I will mark as brain list.​

Answer 1

Answer:

21 cm

Step-by-step explanation:

because 5×2 is 10 10+10=20 aprox is 21

Answer 2

Answer:

Step-by-step explanation:

Yatin have three identical tapes in the form of rectangle.

Given length of the rectangle tape = 5 cm

          breadth of the rectangle tape = 2 cm

By observing figure, Area of the new shape thus formed = Area of three rectangle tapes - Area of two squares with side 2 cm

We know that, Area of the rectangle =  Length × Breadth

                         Area of the square = side × side

⇒Area of the new shape thus formed = 3(L×B) - 2(s×s)

                                                                 = 3(5×2) - 2(2×2)

                                                                 = 3(10) - 2(4)

                                                                 = 30 - 8            

                                                                  = 22 sq.cm

∴ The area of the new shape thus formed is 22 square cm.

so, the correct option is C.
