Area of a rectangle can be calculated by multiplying the length by the height.
So:

l x w
3 x 13
39 cm squared

1/2 x l x w
1/2 x 10 x 8

4(-2d-3)=12, someone please solve this for me asap
wlad13 [49]

4(-3 + -2d) = 12

(-3 * 4 + -2d * 4) = 12

(-12 + -8d) = 12

-12 + -8d = 12

-12 + 12 + -8d = 12 + 12

-12 + 12 = 0

0 + -8d = 12 + 12

-8d = 12 + 12

12 + 12 = 24

-8d = 24

d = -3
