frosja888 [35]

Answer:

28 m
15 m
24.8 m
1.0 m

Step-by-step explanation:

The given statement is the scale factor:

$\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}$

This can be rearranged to the formula ...

$\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}$

Filling in the given scale distances, you find the actual distances to be ...

$\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\$

A sheet of cardboard is 1.6 m by 0.8 m. The following shapes are cut from the cardboard: ● a circular piece with radius 12 cm ●

babymother [125]

Answer:

1.17m²

Step-by-step explanation:

Total area of cardboard=

$1.6 \times 0.8 = 1.28m {}^{2}$

Area of circular piece=

$\pi \: r {}^{2} = ( \frac{22}{7} )(0.12) {}^{2} = \frac{198}{4375} m {}^{2}$

Area of rectangular piece=

$0.2 \times 0.15 = 0.03m {}^{2}$

Area of 2 triangular pieces=

$2( \frac{1}{2} \times 0.3 \times 0.1) = 0.03m {}^{2}$

Remaining area of the cardboard= Total area of cardboard - circular piece - 2 triangular pieces

$1.28 - \frac{198}{4375} - 0.03 -0.03 = \frac{21083}{17500} =1.17m {}^{2}$
