Step-by-step explanation:

width of rectangle(w)=x let

length (l)=4x

perimeter of rectangle=70

2(l+w)=70

2(4x+x)=70

8x+2x=70

10x=70

x=70/10

x=7

again,

length =4x=4×7=28cm
width=x=7

area of rectangle =l×w

7×28
196cm²

hope it helps.

Solve for z. 20 − (z + 7) = 0.9

zhannawk [14.2K]

Answer:

x = 12.1

Step-by-step explanation:

20 − (z + 7) = 0.9

Distribute the minus sign

20 -x -7 = .9

Combine like terms

13 -x = .9

Subtract 13 from each side

-x = -12.1

x = 12.1

5120 m/s converted to km/h

tensa zangetsu [6.8K]

Answer:

18,432 Km/ h

Step-by-step explanation:

Using the conversions

• 1 Km = 1000 m

• 1 hour = 60 × 60 = 3600 seconds

Then

5120 m = $\frac{5120}{1000}$ = 5.12 Km and

5.12 Km × 3600 = 18,432 Km / hour
