ale4655 [162]

Answer:

<h2><em><u>120</u></em><em><u> </u></em><em><u>square</u></em><em><u> </u></em><em><u>units</u></em><em><u> </u></em></h2>

Step-by-step explanation:

<em><u>Given</u></em><em><u>, </u></em>

Base of the parallelogram = 10

Height of the parallelogram = 12

<em><u>Therefore</u></em><em><u>, </u></em>

Area of the parallelogram = <em>base</em><em> </em><em>×</em><em> </em><em>height</em><em> </em>

= 10 × 12

= 120

<em><u>Hence</u></em><em><u>,</u></em>

<em><u>Area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>parallelogram</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>120</u></em><em><u> </u></em><em><u>square</u></em><em><u> </u></em><em><u>units</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

Someone please help me on this I'm unsure if my answer is correct
mafiozo [28]

Answer:

A. length = 23 cm; width = 5 cm

Step-by-step explanation:

So if 4 times the width would be 4w and 3 more than would be + 3, the equation would be l = 4w + 3. If the perimeter is 56, then the new equation, 2(4w + 3) + 2(w) = 56 can be formed. This simplifies to 8w + 6 + 2w = 56, then to 10w + 6 = 56, then to 10w = 50, and finally, w = 5. So the width is 5, and now plug it into the first equation.

l = 4(5) + 3, becomes l = 20 + 3, becomes l = 23.

So the dimensions are: length = 23 cm, width = 5 cm.

*And just to be sure, 2(23 + 5) = 2(28) = 56 which is correct.
