A rectangle's length is 6 units greater than its width. write an equation expressing the rectangle's area, a, as a function of w

vladimir1956 [14]

Let the width be w

Width = w
Length = w + 6
Area = a

a = w(w + 6)
a = w² + 6w

Answer: a = w² + 6w

if the diameter of the concentric circles as shown in the given figure are in the ratio 1:2:3 then find the ratio of the areas o

Monica [59]

Answer:

1 : 4 : 9

Step-by-step explanation:

Given the ratio of diameters = a : b , then

ratio of areas = a² : b²

Here ratio of diameters = 1 : 2 : 3 , so

ratio of areas = 1² : 2² : 3² = 1 : 4 : 9

How do you find the area of a triangle when given only the lengths of three sides?

SashulF [63]

Answer:

Use Heron's formula; see below.

Step-by-step explanation:

Use Heron's formula.

Let the sides of the triangle have lengths a, b, and c.

$s = \dfrac{a + b + c}{2}$

$area = \sqrt{s(s - a)(s - b)(s - c)}$

Example:

A triangle has side lengths 3, 4, and 5 units.

Find the area of the triangle.

$s = \dfrac{a + b + c}{2}$

$s = \dfrac{3 + 4 + 5}{2}$

$s = 6$

$area = \sqrt{s(s - a)(s - b)(s - c)}$

$area = \sqrt{6(6 - 3)(6 - 4)(6 - 5)}$

$area = \sqrt{6(3)(2)(1)}$

$area = \sqrt{36}$

$area = 6$
