Answer:
9.5 ft
Step-by-step explanation:
12.4 times 2 is 24.8 feet (this is the two lengths combined)
since the garden is 43.8 feet, subtract. 43.8 - 24.8 = 19
lastly, 19 divided by 2 is 9.5.
Answer: y + 7 = -2/3 (x - 1 )
Step-by-step explanation:
The equation of a line in point - slope form is given as :
= m(
)
Where m is the slope and (
, 
) is the given point
substituting the values into the formula , we have:
y - (-7) = -2/3 ( x - 1)
y + 7 = -2/3(x - 1 )
Answer:
Lateral Surface Area = 472 m²
Total Surface Area = 486m²
Step-by-step explanation:
The above prism is a Triangular prism
a) Lateral Surface Area = Perimeter of the Base × H
H = 29m
Perimeter of the Base = (7m + 7.28m + 2m)
= 16.28m
Lateral Surface Area = 16.28m × 29m
= 472.12 m²
Approximately to the nearest whole number = 472 m²
b) Total Surface Area
Triangular prism =
2 Triangles and 3 Rectangles
1st Triangle = 1/2 × base × Height
= 1/2 × 2m × 7m
= 7m²
2nd Triangle = 1/2 × base × height
= 1/2 × 2m × 7m
= 7m²
1st Rectangle = Length × Width
= 29m × 2m = 58m²
2nd Rectangle =
Length × Width
= 29m × 7.28m = 211.12m²
Length × Width
= 29m × 7m = 203m²
Total surface area = 7m² + 7m² + 58m² + 211.12m² + 203m²
= 486.12m²
Approximately to the nearest whole number = 486 m²
Option A is the correct option
