What’s the answer ? Help! PLEASE!

408

Step-by-step explanation:

4 cm square

Area = s^2

Area = 4^2                         = 16

I don't think you should be counting where the yellow and blue merge.

Yellow Top

Area = L*W

Area = 15*6                       = 90

Yellow bottom                =  90

Yellow Front              

area = L*W

Area = 15*4                       =60

Area yellow Back             =60

Area 2 triangles

Area 1 triangle = 1/2*b*h

b = 3

h = 4

Area 1 triangle = 1/2*4*3      6

Area 2nd triangle =             6

Slanted part of triangle

Area = 6 * 5                       30

Bottome Triangle

Area = L * W

L = 6

w = 3

Area  = 6 *3                       18

Total    426

-3.5 degrees per hour

step-by-step explanation:
