Answer:
D. 108.25 sq in
Step-by-step explanation:
Area of triangle = bh/2
Area of bottom triangle = 4.3(5)/2 = 10.75
Area of a lateral triangle = 13(5)/2 = 32.5
Area of 3 lateral triangles = 3(32.5) = 97.5
Total surface area = 10.75 + 97.5 = 108.25
12x+6=9x-15 (subtract variables, smaller one)
-9x. -9x
3x+6=-15 (subtract 6 to both sides)
-6. -6
3x=-21 (divide 3)
x=-9
Answer:
according to my equation it is 61.6
The length of the rectangle is 26ft.
What is the perimeter of a rectangle?
- The sum of all sides of a rectangle is the perimeter of the rectangle.
- A rectangle has two equal lengths and two equal widths.
- Therefore, the perimeter 'P' of a rectangle is the sum of two equal lengths and two equal widths.
- That is, 'P=2l+2w' where 'l' is the length and 'w' is the width of the rectangle.
<h3>What is the length of the rectangle with perimeter 96ft and the width 22ft?</h3>
The perimeter of a rectangle is, P = 96 ft.
The width of the rectangle is, w = 22ft.
As we know the perimeter P of a rectangle is given by the formula, P=2l+2w
Therefore, substituting the values in the equation we get,
P = 2l + 2w
96 = 2l + 2*22
96 = 2l + 44
2l = 96 - 44
2l = 52
l = 52/2
l = 26
Hence, the length of the rectangle is 26ft.
