Answer:
24.25 in²
Step-by-step explanation:
s = (a + b + c)/2 = (8 + 13 + 7)/2 = 14 in
s - a = 6, s - b = 1, s - c = 7
so
the area =

Answer:
94.18
Step-by-step explanation:
Given in the question a semi circle and a right angle triangle
Step 1
Find the diameter of the semi circle
To find the diameter we will use pythagorus theorem
<h3>hypotenuse² = height² + base²</h3>
here,
hypotenuse will be diameter of semicircle
height = 9
base = 4
Plug values in the formula above
diameter = √(9²+4²)
diameter = √97
Step 2
Find radius
<h3>radius = diameter / 2</h3>
Step 3
Area
<h3>π(r)²</h3>
π(√97/2)²
= 76.18
Step 4
Total surface area = area of circle + area of right angle triangle
= 76.18 + 1/2(9)(4)
= 94.18

Step-by-step explanation:

The width of rectangle is 30, and the length is 69.
<h3>
What is Rectangle?</h3>
A rectangle is a quadrilateral. The opposite sides of a rectangle are equal and parallel to each other. The interior angle of a rectangle at each vertex is 90°. The sum of all interior angles is 360°. The diagonals bisect each other.
Here, lets say x is equal to the width of the room
then, that means the length is (9+2x) So,
198 = 2x+2(9+2x)
Using the distributive property, we know that
2(9+2x)=18+4x
If you don't know what that is, then go search it up :/
so,
198 = 2x+18+4x
198=6x+18
180=6x
30=x
Now, we know that the width is 30,
That means the length is 60+9, Which is 69.
Thus, the width of rectangle is 30, and the length is 69.
