How do you write algorithm to find the area of a rectangle?

Answer 1

You will need to define the input and times length by width.

For example: L - Length & W - Width

start

sum = 0

input L, W

sum = L * W

print "The area of the rectangle is: SUM"

end

Answer 2

main

{

int l,b,s,ch;

printf("\n menu options:");

printf("\n 1.rectangle:");

printf("\n 2.square:");

printf("\n enter your choice");

scanf("%d",&ch);

switch(ch)

{

case1:printf("\n enter the length and breadth:");

scanf("%d%d",&l,&b);

printf("\n area=%d",l*b);

printf("\n perimeter=%d",2*(l*b));

break;

case2:printf("\n enter the side:");

scanf("%d",&s);

printf("\n area=%d",s*s);

printf("\n perimeter=%d",4*s);

break;

default:printf("\n invalid value");

}

}

Answer 3

start

sum = 0

input L, W

sum = L * W

print "The area of the rectangle is: SUM"

end

Answer 4

Start

1.accept L

2. Accept W

3. A=L×W

4.print A

6. Stop

Answer 5

To find the area of a rectangle you mutiply the base times the height. A=BH -jessica

Answer 6

Convert all unit length (width and length) to feet and then find the area (width * length) as normal.

Answer 7

LW = A 2 inches tall x 2 inches wide = 4 inches in area

L x W = A

L = 2

W=2

A =4

Answer 8

1 start

2 Accept L

3 Accept w

4 A= L×W

5 print A

6 stop

Answer 9

1 start

2 Accept L

3 Accept w

4 A= L×W

5 print A

6 stop

Answer 10

Multiply the length x the width.
