Answer:

34 square cm.

Step-by-step explanation:

I am assuming by the number of measurements given that the shape is a rectangle.

$\text {Formula for area of a rectangle: }A = w * l$

With 4 as the width and 8.5 as the length:

$4*8.5 = 34$

The rectangle should be $34cm^2.$

Vilka [71]

We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

$\frac{l}{2}$

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

$\frac{l}{2}-4$

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation

$w=\frac{l}{2}-4$

If 124 is subtracted from the square of a number the result is 200 what is the number

BartSMP [9]

Answer:

x=18

Step-by-step explanation:

let the number =x

then

x²-124=200

x²=200+124

x²=324

x=18

Sara can complete 3/4 of a puzzle in 7/8 of an hour. How much a puzzle can she complete in an

8090 [49]

Answer:

x = 6/7 of a puzzle

Step-by-step explanation:

Number of puzzle : time taken

= 3/4 : 7/8

How much a puzzle can she complete in an hour?

Let

x = number of puzzle to complete

Number of puzzle : time taken

= x : 1

Equate both ratios to solve for x

3/4 : 7/8 = x : 1

3/4 ÷ 7/8 = x / 1

3/4 × 8/7 = x / 1

24/28 = x / 1

Cross product

24 * 1 = 28 * x

24 = 28x

x = 24/28

= 6/7

x = 6/7 of a puzzle

Step-by-step explanation:

<h3>Given,</h3>

GRAM is a parallelogram
m<GMA = 66°
m<GRP = 32°
m<PAM = 41°

<h3>Solutions:</h3>

i) Since,

Angles on the same side of a transversal in a parallelogram, there sum is 180° so,

<RGM + <GMA = 180°

=> <RGM = 180° - <GMA

=> <RGM = 180° - 66°

=> <RGM = 114° (Ans)

ii) Since,

Opposite angles of a diagonal as a transversal (here RM) are equal so,

<GRP = <PMA = 32°

As we have <GMA = 66° so,

=> <GMP = <GMA - <PMA

= 66° - 32°

=> <GMP = 34° (Ans)

iii) Since,

Opposite angles of a parallelogram are equal so,

<RGM = <RAM = 114°

As we have <PAM = 41° so,

=> <GAR = <RAM - <PAM

= 114° - 41°

=> <GAR = 73° (Ans)

iv) Since,

We got <PMA = 32° and <PAM = 41°, so by angle sum property of a triangle PMA,

=> <MPA = 180° - 32° - 41°

=> <MPA = 107° (Ans)
