8m
1.1.1 Calculate the perimeter (in m) of the Western wall.
Hint: Perimeter of rectangle = 2(length) + 2(breadth)
(2)
1.1.2 Calculate the area (in m?) of the Western wall to be painted.
Hint: Area of rectangle = length x breadth
(4)

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer

h * s * a

h = history teacher

s = science teacher

a =   art teacher.

i see no data table, but just multiply the number of history teachers, science teachers, and art teachers.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
