I have a rectangle with a length of 7 cm and a perimeter of 38 cm. Find the area of the rectangle?

Alex17521 [72]

Answer:

area is 84

Step-by-step explanation:

perimeter is 38(p)

length (l) is 7cm

width is?(w)

p=2(l+w)

38=2(7+w)

38=14+2w

2w=38-14

2w=24

w=12

area=l*w

12*7

=84

Step-by-step explanation:

See the drawing attached

<h3>Given</h3>

C is midpoint of AB
B is between A and D
AD = 15
BD = 7
Find CD

<h3>Solution</h3>

CD = CB + BD =
1/2AB + BD =
1/2(AD - BD) + BD =
1/2(15 - 7) + 7 =
1/2(8) + 7 =
4 + 7 =

Follow the directions to solve the system of equations by elimination. 8x + 7y=39 4x – 14y = -68

harina [27]

Step-by-step explanation:

Hey there!

Here;

The equations are;

$8x + 7y = 39.......(i)$

$4x - 14y = - 68..........(ii)$

Multiplying equation (i) by 2.

16x + 14y = 78

4x - 14y = -68

20x = 10

$x = \frac{10}{20}$

x = 1/2.

Putting value of 'x' in equation (i).

$8 \times \frac{1}{2} + 7y = 39$

$4 + 7y = 39$

$7y = 3 9 - 4$

$y = \frac{35}{7}$

Therefore the value of y is 5.

Check:

Put value of x and y in equation (i).

8x + 7y = 39

$8 \times \frac{1}{2} + 7 \times 5 = 39$

$4 + 35 = 39$

$39 = 39$

(True).

Therefore, the solution is ; (1/2,5).

Hope it helps...
