Answer :

Perimeter
Well the square would be 18+18+13+13 = 62. And the rectangle would be 12+6+12+6 = 36
So combined they would be 62+36 = 98

Area
18 x 13 = 234 for the square and 12 x 6 = 72 for the rectangle which altogether is 234+72= 306

Answer:

368 units

Step-by-step explanation:

Well let’s start with the square.

square)

Dimensions: 18 and 13

Area 18*13 = 234

Perimiter: 18+18+13+13

= 62

234 + 62

= 296

rectangle)

Dimensions: 12 and 6

Area: 12*6 = 36

Perimiter: 12+12+6+6

=36

36 + 36

= 72

72+296

=368

Thus,

the sum of both areas and perimeters is 368units.
