Question

answer the following questions step by step ​

Answer 1

Explanation:

9.) Perimeter of square = 4×side

side = 84/4 = 21m

Area = side² = 21×21 m² = 441 m²

10.)

Volume of tray= 3×4×8 cm³ = 96 cm³

Volume of ice cube = 2×2×2cm³ = 8 cm³

Therefore, No of cubes = 96/8 = 12

Answer 2

Answer:

9. let side be x m

x *4 = 84

therefore, x = 21 m

now area = 21*21

441 m².

10. Volume of ice cube = 2*2*2 = 8cm³

volume of ice tray = 3*4*8= 96 cm³

no. of cubes = 96/8

= 12 cubes.
