A rectangular park is 50m long and 35m broad.A 3.5m broad pavement runs along the boundary of the park .Find the cost of cementi
2 answers:
Solution:
<u>Step-1: Find the area of the park.</u>
- 50 x 35 = Area of park
- => 1750 m² = Area of park
<u>Step-2: Find the area of the inside rectangle.</u>
- (50 - 7)(35 - 7) = Area of inner park
- 43 x 28 = Area of inner park
- 1204 m² = Area of inner park
<u>Step-3: Subtract the area of the inner park from the area of the park.</u>
- 1750 - 1204 = Area of pavement
- => 546 m² = Area of pavement
<u>Step-4: Find the cost per square.</u>
- $400 = 8 m²
- => 1 m² = $50
<u>Step-5: Multiply 546 and 50 to find the cost.</u>
- 546 x 50 = Cost of pavement
- => $27300 = Cost of pavement

Answer:
6084 .
Step-by-step explanation:
Please find the attachment.
We have been given that the home-office of Tri-star industries is made up of three square buildings, one for each department, with a triangular atrium in the middle. The area of the Plumbing building is 5,184 and the area of the A/C building is 900
.
We know that area of square is square of its side length. Since all building are squares, so to find the area of electrical building, we will use Pythagoras theorem.
We can see from our attachment that side length of electrical building is hypotenuse (c) of the right triangle.
Upon substituting our given information in Pythagoras theorem, we will get:
Therefore, the area of electrical building is 6084 square feet.
