Answers

Answer:

B = 12.8 cm (to 1.d.p)

D = 24.1 cm (to 1.d.p)

Step-by-step explanation:

Using Pythagoras Theorem:

B: 4^2 + 3.5^2 = 28.25

square root 28.25 = 5.3 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle B = 12.8 cm (to 1 decimal place)

D: 10^2 - 6.5^2 = 57.75

square root 57.75 = 7.6 (to 1 decimal place) so this is the length of the missing side.

To find perimeter add sides a, b and c so...

perimeter of triangle D = 24.1 cm (to 1 decimal place)

The blueprint for an office building uses a scale of 2 cm.:3.5 m. The height of the actual office building is 259 m. What is the height of the office building on the blueprint?

Answers

Answer:

150 cm

Step-by-step explanation:

So the scale is 2 cm on the blueprint = 3.5 meters in real life.

Basically you can just divide the height of the building by 3.5 meters:

259/3.5=75

There are 75, 3.5 meters in 259 meters

Since 3.5 meters on the print is 2 cm

You need to multiply the number of 3.5 meters by 2:

75*2=150

150 cm
