Question

the following area model shows 2 × 459 broken into parts. the image is not drawn to scale. 400 50 9 2 a b c find the area of each rectangle. a = b = c = find the total area. 2 × 459 =

Explanation:

Step1: Calculate area of A

Multiply 2 by 400.
$2\times400 = 800$

Step2: Calculate area of B

Multiply 2 by 50.
$2\times50=100$

Step3: Calculate area of C

Multiply 2 by 9.
$2\times9 = 18$

Step4: Calculate total area

Add A, B and C.
$800 + 100+18=918$

Answer:

$A = 800$
$B = 100$
$C = 18$
$2\times459 = 918$
