Answer:
552
Step-by-step explanation:
when the sum of 3+10+17+24+498 is done it becomes 552
Call the length a, the width b
Perimeter = (a+b) x 2
And since we have (a+b) x 2 = 43.6, a + b = 43.6 : 2 = 21.8
a + b = 21.8
a - b = 7
-> a + b + (a - b) = 28.8
2a = 28.8
a = 14.4
b = 7.4
So, the area of the rectangle is 14.4 x 7.4 = 106.56
So even just multiplying 3x2 by 6x we know it has to be D because it’s the inly one with 18x3 but i went ahead and worked out the whole problem using the box method
it’s in the attached picture
