Answer:

Length=7units\\\\Width=5units

Step-by-step explanation:

Width=(Length-2) units

W=(L-2) units

Area of the rectangle= 35 square units

Area = length* Width

35= L*(L-2)\\\\35=L^2-2L

Subtracting 35 both sides:

L^2-2L-35=0

Solving the quadratic equation for 'L' ;

Using factorization:

L^2+5L-7L-35=0

Taking common from the equation :

L(L+5)-7(L+5)=0\\\\(L+5)(L-7)=0\\\\L+5=0\\\\L=-5

OR

L-7=0\\\\L=7

The length cannot be negative, therefore Length(L)= 7

Width=Length-2\\\\=7-2\\\\=5 units

Length=7units\\\\Width=5units

Answer:

Let’s find out...

Step-by-step explanation:

21 x 13 = 273

(13 x 20) + (13 x 1) =

260 + 13 = 273

So this one matches

(21 x 10) + 213 =

210 + 213 = 423

Does not match

(30 x 13) - (9 x 13) =

390 - 117 = 273

This one matches

(20 x 10) + (1 x 3) =

200 + 3 = 203

Does not match
