Lady bird [3.3K]3 years ago

Answer:

40 cm

Step-by-step explanation:

Since the figures are similar then the ratios of corresponding sides are equal, that is

\frac{4x}{x} = \frac{48}{x+2}, simplifying gives

4 = \frac{48}{x+2}

Multiply both sides by (x + 2)

4(x + 2) = 48 ( divide both sides by 4 )

x + 2 = 12 ( subtract 2 from both sides )

x = 10

Hence

width = 4x = 4 × 10 = 40

Find the area A of polygon CDEFGH with the given vertices. C(0,5), D(2,5), E(2,3), F(3,2), G(-1,2), H(0,3)
enot [183]

Answer:

<em>The area of the polygon CDEFGH is 7</em>

Step-by-step explanation:

<u>Area of a Polygon</u>

The area of a polygon is generally calculated as the sum of the smaller areas that form its full shape, give each partial area has a known shape, like a square, rectangle, triangle, circle, etc.

The six points given in the question are plotted in the image below. They form a polygon whose area can be divided into two smaller shapes:

The area CDHE is a square of length side 2. Area of a square:

A1=L^2

The area HEFG is a trapezoid with bases lengths 4 and 2,  and height 1. Area of a trapezoid:

\displaystyle A2=\frac{b1+b2}{2}h

Calculate both areas:

A1=2^2=4

\displaystyle A2=\frac{2+4}{2}\cdot 1=3

Total Area=4+3=7

The area of the polygon CDEFGH is 7

Find the value of the variable if P is between J &amp; K. <br><br> JP = 2x ; PK = 7x ; JK = 27
Nana76 [90]
J ---- P --- K

JP = 2x
PK = 7x
JK = 27

2x + 7x = 27
9x = 27
x = 27/9
x = 3

The value of P is 3.

JP = 2x = 2(3) = 6
PK = 7x = 7(3) = 21

Which is the correct formula to find the area of ABC?
Alex777 [14]

Answer:

none of them

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = 0.5 × base × perpendicular height

Here the base is BC and perpendicular height is AD, hence

Area of ΔABC = 0.5 × BC × AD
