The length of a rectangle is 3 times its width. the rectangle’s width is 4 m.

what is the area of the rectangle?

enter your answer in the box.

Step-by-step explanation:

Given that,

Width of the rectangle, b = 4 m

The length of the rectangle, l = 3b = 3(4) m = 12 m

Let A is the area of the rectangle. It is given by :

So, the area of the rectangle is . Hence, this is the required solution.

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length

1/6
