Answer:
<h2>122.5</h2>
Step-by-step explanation:
the parameter of B figure is
12+9+9+5
35
as we know the scale factor is 7/2
so the parameter of A figure is
35×7/2
122.5
Answer:
Product, twice and area
Step-by-step explanation:
The product is the result of the multiplication of the factors.
Product = answer to a multiplication problem
Twice means multiply by 2
Area is found by multiplying the dimensions of a plane figure.
The area of the two triangular bases is
(total base area) = 2×(1/2)bh
= bh
= (10 m)(6 m) = 10·6 m² = 60 m²
The area of the three rectangles making up the remaining faces of the prism is
(total lateral area) = length×base + length×height + length×hypotenuse
= length×(base + height + hypotenuse)
= (16 m)(10 m + 6 m + 11.6 m)
= (16 m)(27.6 m) = 16·27.6 m² = 441.6 m²
Then the surface area of the prism is the sum of these
surface area = total base area + total lateral area
= 60 m² + 441.6² = 501.6 m²
When rounded to the nearest whole number, this is
A) 502 m²
