Key to this problem! Distribution!

-7x(11x+12)

Imagine -7x going to both 11x and 12. Meaning it would multiply with both those numbers. If helpful, write arrows that it goes to both numbers inside the parenthesis to help you out.

-7x(11x)+12(-7x)

-7 x 11 is -77, and x times x is x^2, so the first part would equal to -77x^2

12 x -7 is -84, and add a x to get -84x.

The final answer is -77x^2-84x

The area of a rectangle is 259 cm2 and its lenght is 18.5 cm find

crimeas [40]

The breadth of rectangle is 14 cm

The perimeter of rectangle is 65 cm

<em><u>Solution:</u></em>

Given that,

Area of rectangle = 259 square centimeter

Length of rectangle = 18.5 cm

<em><u>The area of rectangle is given by formula:</u></em>

$Area\ of\ rectangle = length \times breadth$

<h3><u>Find the breadth:</u></h3>

Substitute the given values in above formula:

$259 = 18.5 \times breadth\\\\breadth = \frac{259}{18.5}\\\\breadth = 14$

Thus breadth is 14 cm

<h3><u>Find the perimeter:</u></h3>

The perimeter of rectangle is given by formula:

$Perimeter = 2(length + breadth)$

Substitute the given values in above formula:

$perimeter = 2(18.5+14)\\\\perimeter = 2(32.5)\\\\perimeter = 65$

Thus perimeter of rectangle is 65 cm
