Answer:

Step-by-step explanation:

-3(x+7)=5

Answer:

422

Step-by-step explanation:

Large rectangle

A = 2(lw+wh+lh)

A = 2(7*10+10*5+7*5)

A = 310

Small rectangle

A = 136

Now the squares that connect both, 4*3

Since you have 1 on each rectangle, the total area for this is 24

add 310 + 136 and substract 24
