<u>Answer</u>:

x = 22.5

<u>Explanation</u>:

Given Sides:

  • HB = 6
  • HD = 6+15 = 21
  • HM = 9
  • HT = 9 + x

-----------------------------

using all these sides, create similarities equation:

\frac{HB}{HD}  = \frac{HM}{HT}

\frac{6}{21}  = \frac{9}{9+x}

6(9+x) = 9(21)

54 + 6x = 189

6x = 189 - 54

6x = 135

x = \frac{135}{6}

x = 22.5

Find the perimeter of this figure to the nearest hundredth
Alja [10]

Answer:

The perimeter of given figure = 56.56 ft

Step-by-step explanation:

Step(i):-

From diagram

The length of the rectangle = 10 ft

The width of the rectangle = 8 ft

Perimeter of the rectangle

= 2 ( l+w)

= 2 ( 10 + 8)

= 2 × 18

= 36

Step(ii):-

The semi circle is included in the given diagram

Now we will find the perimeter of semicircle

We know that

perimeter of the circle

p = 2πr + d

perimeter of the semicircle

P = πr + 2 r (∵ d = 2 r)

Step(iii):-

From diagram the diameter of semicircle is equal to the width of the rectangle

d = 8

d = 2 r = 8

The radius of the circle 'r' = 4

perimeter of the semicircle

P = πr + 2 r

P = 3.14 ( 4) + 8

P= 20.56

Conclusion:-

The perimeter of given figure

= perimeter of rectangle + perimeter of semicircle

= 36 + 20.56

=56.56 ft
