The answer to this question is:

Size of a square's side = 11 cm

A Square is a flat geometric shape with four right angles and equal sides. The square's four sides are equal to one another or congruent. The square's opposing sides run parallel to one another. The square's diagonals form a 90° angle with one another. The two diagonals of the square are equivalent to one another. The square is made up of four vertices and four sides.

Area of square = ( Side )²

Given that:

Area of square = ( Side )² = 121 cm²

Dimensions of a square's side = √ Area

so, the length of the square's side = √ 121

= √ 11*11

= √ ( 11 )²

= 11

Thus, side of the square = 11 cm

Therefore, side length of square = 11cm

Factorise : x^2+x-72 Step by Step

Ivan

Answer:

(x + 9)(x - 8)

Step-by-step explanation:

f(x) = x^2 + x - 72

= x^2 - 8x + 9x - 72

= (x^2 - 8x) + (9x - 72)

= x(x - 8) + 9(x - 8)

= (x + 9)(x - 8)

The height of a triangular window is 3 feet less than its base. The area the window is 20 ft.? find the dimensions of the window

Ivenika [448]

Let us assume base of the window = b feet.

Height is 3 feet less than base, that is = (b-3).

Given area of the triangle = 20 feet square.

We know formula for area of a triangle:

Area = $\frac{1}{2}$ × Base × Height

Plugging values in formula, we get

20 = $\frac{1}{2} b \times (b-3)$

$\mathrm{Multiply\:both\:sides\:by\:}2$

$40=b\left(b-3\right)$

$40=b^2-3b$

$b^2-3b-40=0$

Factoring quadratic, we get

$\left(b+5\right)\left(b-8\right)$ =0

b+5=0

b=-5

b-8=0

b=8.

For base we can take only positive value.

<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>
