Answer:
225
Step-by-step explanation:
First, find the area of the sqare so 5x5 would be 25.
Next, find the area of the triangle, the formula for that is 1/2 base x height. Here the base is 5 in and the height is 20 so that would be (5 x 20) 1/2 which equals 50. Then, because there are 4 triangles multiply the fifty 4 times, 200.
Then take the 25 from the square and add it to the 200 to get your answer of 225!
Answer:
$2690 hopefully you get that [the picture]
Numbers x and y
sum of the two = 16: x + y = 16
difference of the two = x - y = 6
solve one of the equations for one variable:
I'm going to solve x - y = 6, for x
(x - y) + y = 6 + y, x = y + 6
Now plug that into the other equation:
x + y = 16, (y+6) + y = 16
(y+y) + 6 = 16
2y + 6 - 6 = 16 - 6
2y = 10
2y/2 = 10/2
y = 5
Now plug that solved y-value into either original equation: x - y = 6, x - 5 = 6
(x-5) + 5 = 6 + 5
x = 11
So now we have their values: x=11, y=5
But always double-check what the question asked... What is their product??
So x*y = 11*5 = 55
