if there's eight students on the minibus then there's 4 boys and 4 girls on the minibus
Answer:
length = 26 cm
width = 4 cm
Step-by-step explanation:
A = 104 cm²
A = length x width
ratio of length and width = 13 : 2
total ratio of length and width is 15 = a
so ratio of length is (13/15)a and width (2/15)a
A = length x width = (13/15)a x (2/15)a = (26/225)a² = 104
a² = 104 x 225 : 26 = 900
a = 30cm
length = (13/15)a = 13/15 x 30 = 26 cm
width = (2/15)a = 2/15 x 30 = 4 cm
The middle row is long on one side and short in the other side which is the shape of a rectangle.
The net is a rectangular prism
57.8 ≈ 60
81 ≈ 80
57.8/ 81
≈ 60/80
≈ 3/4
≈ 0.75
The quotient 57.8/ 81 is approximately equal to 0.75~
