A meter stick casts a shadow 1.4 m long at the same time a flagpole casts a shadow 7.7 m long.  The triangle formed by the meterstick and its shadow is similar to the triangle formed by the flagpole and its shadow.  How tall is the flagpole?

Answers

These two triangles are similar, so their ratios are equal.

7.7 / 1.4 = x / 1, where x = the flagpole length
multiply by one and simplify
x = 7.7 / 1.4

the length of a rectangle is 3 times the width. The perimeter is 44 cm. What are the dimensions of the rectangle?

Answers

Hello there
We can say that,
The length = 3u
The width= 1u
3u + 1u +3u +1u= 44cm
8u= 44cm
1u= 44cm / 8
    = 5.5cm
Length= 5.5 cm x 3
           =16.5 cm
Width= 5.5 cm

Hope this helps :))
