The surface area is 33 units.

Step-by-step explanation:

The base is 3 x 3 so 9.

There are four tringles, two triangles equals a square / rectangle.

So  2 (4 x 3) = 24

24 + 9 = 33

33 units²

Step-by-step explanation:

From the net, we can see that the surface area consists of four triangles and one square:

Surface area = 4(area of triangle) + (area of square)

The base of the triangles (b) = 3, and their perpendicular height (h) = 4.

Area of triangle = (1/2)bh

Area of triangle = (1/2)(3)(4)

Area of triangle = 6

The square has side length (L) 3.

Area of square = L²

Area of square = 3²

Area of square = 9

Surface area = 4(area of triangle) + (area of square)

Surface area = 4(6) + (9)

Surface area = 24 + 9

Surface area = 33

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
