Answer:
31.5 units^2
Step-by-step explanation:
Rectangle area (RA) = l × w
Triangle area (TA) = (bh)/2
RA = 3 × 7
RA = 21
TA = (7 × 3)/2
TA = 21/2
TA = 10.5
(Triangles are congruent as shown by the lines on each side of the triangle so I can calculate area of both of them together as I just did)
Add areas together
21 + 10.5 = 31.5
Answer:
V≈5.58ft³ d=2.2 ft
Step-by-step explanation:
V=4 3πr3
d=2r
Solving for V
V=1 6π d3 =1 6·π·2.23≈5.57528ft³
Hope this helps! :D
The length of the rectangular section of the roof is 25 m
<h3>Calculating area </h3>
From the question, we are to determine the length of the section of the roof
From the given information,
The area of the rectangular section = 180 m²
The width of the rectangular section = 7 1/5 m = 7.2 m
Using the formula for area of a rectangle
A = l × w
Where A is the area
l is the length
and w is the width
Then,
180 = l × 7.2
l = 180/7.2
l = 25 m
Hence, the length of the rectangular section of the roof is 25 m
