Step-by-step explanation:
Given that,
Length, l = (3d+2) m
Width, b = (d+5) m
(a) Perimeter of the rectangle,
P = 2(l+b)
P = 2(3d+2+d+5)
= 2(4d+7)
P = 8d+14
(b) If P = 30 cm.
8d+14 = 30
8d = 16
d = 2
(c) l = (3(2)+2) = 8 m
b = (2+5) = 7 m
The area of this rectangle,
A = lb
A = 8×7
A = 56 cm²
Hence, this is the required solution.
Answer:
792.9 in²
Step-by-step Explanation:
Given:
Area of the base of the regular hexagonal prism box (B) = 85.3 in²
Each side length of hexagonal base (s) = 5.73 in
Height of prism box (h) = 18.10 in
Required:
Surface area of the wood used in making the hexagonal prism box
SOLUTION:
Surface area for any given regular prism can be calculated using the following formula: (Perimeter of Base × height of prism) + 2(Base Area)
Perimeter of the hexagonal base of the prism box = 6(5.73) (Note: hexagon has 6 sides.)
Perimeter of base = 34.38 in
Height = 18.10 in
Base area is already given as 85.3 in²
Surface area of the hexagonal prism box ![= (34.38*18.10) + 2(85.3)](https://tex.z-dn.net/?f=%20%3D%20%2834.38%2A18.10%29%20%2B%202%2885.3%29%20)
![= 622.278 + 170.6 = 792.878 in^2](https://tex.z-dn.net/?f=%20%3D%20622.278%20%2B%20170.6%20%3D%20792.878%20in%5E2%20)
<em>Surface area of the wood used in making the jewelry box ≈ 792.9 in²</em>
