What’s the surface area for this figure? (If u can please help!)

172cm^2

Step-by-step explanation:

Surface Area of Triangles;

A=B x H / 2

  =(4x3) /2

  = 6cm

 Multiply 6 by 2 since there are two triangles at both ends

6 x 2 =12cm^2

Surface area of the rectangles;

A=LW

  =10x5

  =50cm

Multiply by three since there are three triangles

50cm x 3 = 150cm^2

Add everything both total triangle and rectangle surface areas together

A= 12 + 150

  =172cm^2

–0.91

Step-by-step explanation:

The correlation coefficient for this data set will be negative, since the dependent variable decreases as the independent variable increases.

Since the data appears to be fairly linear, the correlation coefficient will be close to 1; this means -0.91 is our best choice.
