Answer: 172 square meter square

Step-by-step explanation:

Area of Rectangular prism is given as :

A = 2 (wl + hl + hw)

Where :

w = width

h = height

l = length

Calculating the area of rectangular prism given , the shape given is divided into six segments , each segment is a triangle , all we need to do is to find the area of each segment and add.

Area of the first segment = 7 x 8 = 56 ( there are 7 boxes horizontally and 8 boxes vertically)

second segment = 2 x 8 = 16

third segment = 7 x 8 = 56

fourth = 2 x 8 = 16

fifth = 2 x 7 = 14

sixth segment = 2 x 7 = 14

Therefore , area of the rectangular prism will be

A = 56 + 16 +56 + 16 + 14 + 14

A = 172

Point D is between Points E and F. DE = 3x + 9, DF = 12x - 1<br> and EF = 38. Find DE and DF.
jarptica [38.1K]

Answer:

DE = 15

DF = 23

Step-by-step explanation:

E___D___F

EF = DE + DF

38 = (3x +9) + (12x-1)

38 = 15x + 8

15x = 38 - 8

15x = 30

x = 30/15

x = 2

DE = 3x + 9 = 3(2) + 9 = 6 + 9 = 15

DF = 12x - 1 = 12(2) - 1 = 24 - 1 = 23

I hope I helped you^_^
