# What is the area of a square that has sides measuring 8.6 cm?

73.96cm squared

### What is the measurement of the following area 215 feet by 172 feet by 86 feet by 342 feet?

There is no way to answer the question. The wording of the question suggests that it is a quadrilateral area. Unfortunately, quadrilaterals are non-rigid shapes so that the lengths of their sides do not determine their area. To understand the problem consider a square. It can be flexed into a rhombus which can be made so thin that its area is virtually zero!

### What shape has a perimeter of 86 millimetres?

Any shape can have a perimeter of 86 mm. Some examples are: -- a scalene triangle with sides of 25, 30, and 31 mm -- a square with 21.5 mm sides -- an infinite number of different rectangles, like 2 x 43, 3 x 40, 4.1 x 38.9, 5 x 38, 21 x 22, etc. -- a trapezoid with sides of 10, 30, 10, and 36 mm -- a regular pentagon with sides of 17.2…

### What are the interior angles of an isosceles trapezoid whose opposite parallel sides are 3.99 cm and 6.01 cm with an area of 78.25 square cm showing work to an appropriate degree of accuracy?

Area: 0.5*(3.99+6.01)*height = 78.25 sq cm Height: (2*78.75)/10 = 15.65 cm The trapezoid will have 2 right angle triangles each side with bases of (6.01-3.99)2 = 1.01 cm and using the tangent ratio as follows:- Tangent^-1(15.65/1.01) = 86 degrees rounded Base angles are equal therefore the angles are: 86, 86, 94 and 94 degrees

### What would the inches be if a blanket that was 86 inches square?

There is no direct relationship between the area of an object and its linear dimensions. Consider the following: Suppose the length of the blanket, in inches, is any number L which is greater than sqrt(86 sq inches) = 9.27 inches approx. Let W = 86/L inches. Then a blanket with Length L and Width W will have an area of L*W = L*(86/L) = 86 sq inches. Since L can have any one of an…

### How many square feet are in 7ft 2 inches long x 5ft 11 inches wide x 8ft 7 inches high?

Square feet measure area, you're looking for volume, which is cubic feet. 86 x 71 x 103 cubic inches. To get cubic feet divide by 1728 giving 363.96 cuft. If you're wanting to know the surface area of a solid with those dimensions then it is 2 x ((86 x 71) + (86 x 103) + (71 x 103)) ie 44554 sqin or 309.4 sqft
