Question

the image is not drawn to scale. 400 80 3 6 a b c find the area of each rectangle. a = b = c = find the total area. 483×6=

Explanation:

Step1: Calculate area of rectangle A

The length of rectangle A is 400 and width is 6. Area of a rectangle is length times width. So $A = 400\times6=2400$.

Step2: Calculate area of rectangle B

The length of rectangle B is 80 and width is 6. So $B = 80\times6 = 480$.

Step3: Calculate area of rectangle C

The length of rectangle C is 3 and width is 6. So $C=3\times6 = 18$.

Step4: Calculate total area

The total area is the sum of the areas of A, B and C. Also, we can calculate it as $483\times6$. Since $483\times6=(400 + 80+3)\times6=400\times6+80\times6 + 3\times6$. So the total area is $2400+480 + 18=2898$.

Answer:

$A = 2400$
$B = 480$
$C = 18$
$483\times6=2898$
