Area of a parallelogram is A = base times height
Area = 15 * 13 = 195
So, your answer is 195 cm squared
:)))
Given:
A height of 2 feet above the ground and angle of elevation of 86 degrees.
Assuming that the form of our problem is a right triangle, we can solve for the remaining angle:
180 - (90+86) = 4 degrees
The distance from the home plate to the centerfield is
2/sin 4 = x / sin 86
solve for x
x = 28.60 feet

1 Simplify 10n+4-n10n+4−n to 9n+49n+4.
1+4(-6n-4)<9n+41+4(−6n−4)<9n+4
2 Expand.
1-24n-16<9n+41−24n−16<9n+4
3 Simplify 1-24n-161−24n−16 to -24n-15−24n−15.
-24n-15<9n+4−24n−15<9n+4
4 Add 24n24n to both sides.
-15<9n+4+24n−15<9n+4+24n
5 Simplify 9n+4+24n9n+4+24n to 33n+433n+4.
-15<33n+4−15<33n+4
6 Subtract 44 from both sides.
-15-4<33n−15−4<33n
7 Simplify -15-4−15−4 to -19−19.
-19<33n−19<33n
8 Divide both sides by 3333.

The perimeter of a shape is the sum of its side lengths
Becca, Lucas, and Christian are correct
<h3>How to determine the correct perimeter</h3>
The side lengths of the triangle are x, 3x - 4 and 3x - 4
So, the perimeter (P) is:
P = x + 3x - 4 + 3x - 4
The above equation can be rewritten as:
P =2(3x - 4) + x
P = 6x + x - 4
P = (3x - 4) + (3x - 4) + x
P = 7x - 4
Hence, Becca, Lucas, and Christian are correct
