Answer:
A=360in^2
Step-by-step explanation:
there are 5 faces, 2 triangular, 3 rectangular
Triangular:
A=(9 * 10)/2=45
Since there are 2 of them the total is 90 in^2 for the triangles
Rectangular:
A=10*9=90
Since there are 3 the total is 270in^2
Total surface area is A=270+90=360in^2
Here, trapezoid is composed of two triangles, and one rectangle.
So, Area of rectangle = 4 * 7 = 28 cm²
Area of a triangle = 1/2 * 3 * 7 = 21/2 = 10.5 cm²
Area of Trapezoid = area of rectangle + 2(area of triangle)
= 28 + 2(10.5)
= 28 + 21 = 49
In short, Your Answer would be 49 cm²
Hope this helps!
12) LCM of 2 & 12 is 12
Answer: (F)
13) (25 x 8) x 4
Step 1: Order of operations do parenthesis first: (25 x 8) = 200
Step 2: Multiply: 200 x 4 = 800
Answer: 800
14) I would plug each value in to see which works
D) 10x + 5y = 10(6) + 5(9) = 60 + 45 = 105
Answer is (D)
15) 2 x 12 - 8 (divided by) 2^2
Exponent first: 2 x 12 - 8 divided by 4
Multiplication/ Division: 2 x 12 = 24 and -8 divided by 4 = -2
Add/Subtract: 24 - 2 = 22
Answer: (I)

Answer:
60
Step-by-step explanation:
since its a square, and has four sides then you would divide total length by four to find the length of each side
