Answer:

875

Step-by-step explanation:

Rectangle ABCD is SIMILAR to rectangle EFGH this means that they are proportionately the same as each other. Therefore any changes we know about one side apply to the whole shape. Since we know side EF is 5 times side AB we also know side EH is 5 times side AD. If 5 times AD is 35, AD must be 7. Multiply that by five, and you have the value of EH, which is 35. multiply that by EF (25), and you have your answer. Hope this helps!

Answer:

<em>As </em><em>we </em><em>can </em><em>see </em><em>that </em><em>both </em><em>rectangles </em><em>are </em><em>similar</em><em>. </em>

Step-by-step explanation:

AB= 5ft and EF = 25

Area of rectangle ABCD

5 * BC = 35

Therefore BC= 7

Now

The value of FG is 35 ft

hence now we can calculate the area of rectangle EFGH

= 25 *35

= 875 square foot

Answer:

4.56 × 10^ − 3

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

The radius of a semicircle is 3 feet. What is the semicircle's area?<br>Use 3.14 for Pi​
valentinak56 [21]

Answer:

14.13 ft²

Step-by-step explanation:

The area of a semicircle is

=  \frac{\pi \:  {r}^{2} }{2}

We were given the radius of the semicircle to be: r=3 feet.

We were also asked to use π as 3.14.

We substitute into the formula to get:

=  \frac{3.14 \times  {3}^{2} }{2}

This is the same as:

=  \frac{3.14 \times  9}{2}

Or

= 3.14 \times  4.5

= 14 .13 {ft}^{2}

The area of the semicircle is 14.13 ft²
