Calculate the length of the base of a parallelogram if the area is 135cm and it's height is 9cm<br>

Ghella [55]

Answer:

15cm

Step-by-step explanation:

The formula to calculate the area of a parallelogram is base x height.

Since we know the height and area, we can write the equation:

135 = base x 9

Now we can just divide 9 from both sides to solve for base:

135/9=basex9/9

So we get:

Base = 135/9=15

The length of the base is 15cm.

Hope this helped!

Answer:

Step-by-step explanation:

AD = CD { BD is median}

6x + 10 = 2x + 12

6x -2x = 12 - 10

4x = 2

x = 2/4

x = 1/2

AC= AD + CD

= 6x + 10 + 2x +10 {add the like terms}

= 8x + 20 { Now plugin the value of x}

$=8*\frac{1}{2}+22\\\\$

= 4 + 22

= 26
