Answer:
15. (i) 2 x 5 x 8 x 12 = 960 m^2
(ii) 2 x 3 x 4 x 5 = 120 m^2
(iii) 3 x 18 x 21 = 1,134 m^2
16. (i) Perimeter: 14 + 14 + 10 + 10 + 4 + 4 + 8 + 16 = 80 cm
Area: 14 x 10 x 8 x 4 = 4,480 cm^2
(ii) Perimeter: 13 + 13 + 10 + 10 + 5(4) + 3(4) = 78 cm
Area: 13 x 10 x 5 x 3 = 1,950 cm^2
17. (i) 2 x 4 x 6 x 8 = 384 cm^2
(ii) 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 12 x 20 = 9,676,800 cm^2
(iii) 2 x 3 x 5 x 12 x 14 x 18 = 90,720 cm^2
Step-by-step explanation:
Assuming the room is square or rectangular, you would measure the length and width. Multiply the length by the width to get the area (no need to multiply a number if that number is already multiplied)
To find the perimeter, add all the numbers written in the given shape
(double check if my calculations are wrong)
hope it helpss :))
