The perimeter of a rectangle is 24. If the length is 5 times the width, what is the area?
KATRIN_1 [288]

Answer: Area is 20

Step-by-step explanation:

Perimeter of a rectangle is 24

Let the length be x

Let the breadth be Y

Length is 5times the breadth

I.e

X=5y

Formula for perimeter of a rectangle is

2(length + breadth)

= 2(x+y)

Substitute for x=5y

2(5y+y)=24

2(6y)=24

6y=24/2

6y=12

Y=12/6

Y=2

Breadth = 2

Since length =5y

Length=5(2)

Length = 10

Area of a rectangle = length × breadth

Area= 10×2

Area = 20

Area of the rectangle is 20

The partial products are: 42 x 28 = (40 + 2) x (20 + 8) = 40 x 20 + 40 x 8 + 2 x 20 + 2 x 8
= 800 + 320 + 40 + 16 Hope this helped.

How do i solve this?
Xelga [282]

Well this is considerably easy!

Create equivalent expressions in the equation that all have equal bases.

2^x=2^4

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

x=4

Verify each of the solutions by substituting them into 2^x=16

and solving.

x=4
