Answer: The perimeter is 96 m
Step-by-step explanation:
If we tag the length of the rectangle as
and the width as
, and if in addition we are told
,the dimensions of the rectangle are as shown in the figure.
Now, the area of a rectangle is given by:
Since
:
Isolating
:
On the other hand, the perimeter of a triangle is given by the addition of each of its sides. Then, if the rectangle has two sides that measure
and two sides that measure
, the perimeter is:

Substituting the value of
in the last equation:

Finally the perimeter is:

Answer:
10.75 cm^2
Step-by-step explanation:
1. Area of semicircle, A= (pi x R^2) divided by 2
2. A= (3.14 x 5^2) divided by 2 = 39.25
3. Area of rectangle, A= l x w
4 A= 10 x 5 = 50
5. subtract
6. 50 - 39.25
7. 10.75
Answer:
465 in²
Step-by-step explanation:
square area: A = lw
triangle area: A =
lw (or base x height)
= (15)(15) = 225
=
(8)(15) = 60
There is one square and 4 triangles so...
225 + 4(60) = 465 in²
AB
It is indicated in the figure and is valid:
m AB = 49
m ABC
Angle resulting from the following subtraction:
m ABC = 360-107 = 253
m BAC
Angle resulting from the sum of the two angles shown in the figure:
m BAC = 107 + 49 = 156
m ACB
Angle resulting from the following subtraction:
m ACB = 360-49 = 311
