Question

Please help me to solve this

Answer 1

Answer:

5. 7 cm

6. Rita by 15 m

Step-by-step explanation:

5. Perimeter of an octagon = 8 x length of a side

                                            = 56 ÷ 8 = 7cm

6. Rita

Total length she walks = one side of the square x 4

                                      = 30m x 4

                                      = 120m

She walks 120m twice, so 120m x 2

                                       = 240m

Reema

Total length she walks = one side of the triangle x 3

                                      = 75m x 3

                                      = 225m

240 > 225

∴ Rita walks more by 15 meters
