A cuboid measures 2.5 m x 3.8 m x 9.4 m find the length of the diagonal of the cuboid to 2D.P ​

Mathematics
1 answer:
Elanso [62]2 years ago
6 0

Answer:

10.44m

Step-by-step explanation:

Diagonal of a cuboid = ⎷(l2 + b2 + h2)

We have : ⎷(2.5sqr + 3.8sqr + 9.4sqr) = 10.4427008.... (rounded to 10.44)

Hope this helps :)

If one side of a square is increased by 8 cm and an adjacent side decreased by 2 cm, a rectangle is formed whose perimeter is 40
sveta [45]
<h3>Answer:  7 cm</h3>

===========================================================

Explanation:

x = side length of the original square (measured in cm).

One side increases by 8 cm to go from x to x+8. At the same time, an adjacent side decreases from x to x-2 (aka it decreases by 2 cm).

The x by x square turns into a x+8 by x-2 rectangle.

L = x+8 = length

W = x-2 = width

P = perimeter of rectangle

P = 2(L+W)

P = 2(x+8+x-2)

P = 2(2x+6)

P = 4x+12

The perimeter of this rectangle is 4x+12, which is set equal to the stated perimeter 40 cm. We'll use this to solve for x.

P = 40

4x+12 = 40

4x = 40-12

4x = 28

x = 28/4

x = 7

The square originally had side lengths of 7 cm.

Increasing this by 8 cm gets us x+8 = 7+8 = 15 cm. So L = 15.

Also, W = x-2 = 7-2 = 5 cm is the width.

Then note how P = 2(L+W) = 2(15+5) = 40 to help confirm the answer.

The diagonals of a quadrilaretral intersect at (-1,4). One of the sides of the quadrilateral is bounded by (2,7) and (-3,5)
Maurinko [17]

Solution:

Properties of Square

1. All sides are equal.

2. Opposite sides are parallel.

3. Diagonals are equal and bisect each other at right angles.

As, given point of intersection of diagonals of square is (-1,4).

And, One of the sides of the quadrilateral is bounded by (2,7) and (-3,5).  

Drawn the picture of square below,

Let, the third and fourth vertices of square be (x,y) and (p,q).

As, diagonals of square bisect each other. So,

\frac{x+2}{2}=-1\\\\ x +2=-2\\\\ x=-2-2\\\\ x=-4\\\\ \frac{y+7}{2}=4\\\\ y+7=8\\\\ y=8-7\\\\ y=1\\\\ \frac{p-3}{2}=-1\\\\ p-3=-2\\\\ p=3-2\\\\ p=1 \\\\ \frac{q+5}{2}=4\\\\ q+5=8\\\\ q=8-5\\\\ q=3

So, third and fourth vertices are (-4,1) and (1,3).
