(a) Find the area of the original piece of cloth.
(b) find the breadth of the original piece of cloth.
Jawab:
(a.) Area of the original piece = 30 m²
(b.) Breadth of the original piece = 5 m
Penjelasan dengan langkah-langkah:
Given that the area (colored dark) A₁ = 22 m²
Length of the original piece (L) = 6 m
length of the cut out piece (l) = 4 m
breadth of the cut out piece (b) = 2 m
(a.) Find the area before the cloth was cut
Let the used cloth be 'x'
x = l(b)
x = 4(2)
x = 8 m²
Therefore the area before the cloth was cut =
A₁ + x =
22 + 8
= 30 m²
Area of the original piece = 30 m²
(b.) Find the breadth of the original piece (B)
L(B) = 30
6B = 30
B = 30/6
B = 5 m
Breadth of the original piece = 5 m
