Yes it is correct because you would multiply 30 by 7 which equals 210 + the extra 20 dollars / 50 dollars (idk).. she will have more than enough though
The surface area of prism is 185.815 square inches
<em><u>Solution:</u></em>
Given that,



<em><u>The surface area of package is given as:</u></em>

Where,
"l" is the length
"w" is the width
"h" is the height
<em><u>Substituting the values we get,</u></em>

Thus the surface area of prism is 185.815 square inches
Answer:
735 cm²
Step-by-step explanation:
The figure is a trapezium .The area of the triangle section can be calculated using the Heron's formula.
The other part of the figure will be a square of sides 21 cm by 21 cm
<u>Area of the square section</u>
Area = l²
Area = 21* 21 = 441 cm²
<u>Area of the triangle using Heron's formula</u>
Sides of the triangle are ;
a= 28 cm
c= 35 cm
b = 21 cm -----height of the trapezium
The Heron's formula is given as;

where s is half the perimeter of the triangle
Perimeter of the triangle is given as ;
P= 35 + 28 + 21 =84 cm
s= 84/2 = 42 cm

Total area = 294 + 441 = 735 cm²
2s+3<15
-3<15-3
2s<12
2 < 2
s<6
