Question

The rectangle shown has a perimeter of 54 cm and the given area. Its length is 3 more than 3 times its width. Write and solve a system of equations to find the dimensions of the rectangle.

The length of the rectangle is what cm ?
the width of the rectangle is
what cm.?

Answer 1

Explanation:

the perimeter P=2(L+W)=54

P=2L+2W=54 OR L+W=27

we know that L=3W+3

P=3W+W=27-3

4W=24

W=6 CM

L=21CM
