finding x

3x-2=x+6

2x=8

x=4

perimeter;

3[4]-2=10

width=10cm

length=

4+6=10

length =10

perimeter=2[l+w]

2 [10 +10]

perimeter=40cm

finding area;

area = l x w

10 x 10  =100cm²

Step-by-step explanation:

step-by-step explanation:

(3rd option) - c

hence, the required result is

step-by-step explanation:

suppose we have two matrices a and b

we will assume the two matrices

we have to compute b-a which means subtracting corresponding elements of a from b.
