Answer:
Step-by-step explanation:
Area of one road = 700 x 10
7000 sq m
area of another road
= 300 x 10 = 3000sq m
Total area of road
= 7000 + 3000 - 10 x 10
= 9900 sq m
Area of park
= 700 x 300
= 210000 sq m
less area of road
= 210000 - 9900
= 200100 sq m
= 200100 / 10000 hectare
= 20.01 hectare.
Answer:
1. Area of rectangular rug is
2. Area of triangular room is
Step-by-step explanation:
This problem bothers on the mensuration of flat shapes, rectangle and triangle.
step one
let us start by solving for the area of the rectangular rug
given data
Area A = ?
Length l = 11 ft
Width w= 10 ft
we know that the area of a rectangle is expressed as
substituting our given data we have
step two
let us solve for the area of the triangular room
given data
Area A = ?
base b = 30 ft
height h= 22 ft
we know that the area of a triangle is expressed as
substituting our given data we have
The ramp will form a triangle with height 2ft and base 6ft.
The length of the ramp will be the hypotenuse of this triangle.
length² = height² + base²
length = √(height² + base²)
length = √(2² + 6²)
length = √(4 + 36)
length = √40
length = 6.3ft
Therefore, the ramp will be 6.3ft long.
