Braelyn Is writing including to officiate rectangle with a width equal to half the length she knows the perimeter is equal to 18 units and needs to find the length and width of the rectangle
the formula to find the perimeter in a rectangle is 2(L+W)=perimeter they gave us the perimeter so we substitute is into the equation: 2(L+W)=18 substitute the W by 1/2L u will end up with 2(L+1/2L)=18 distribute the 2 and u will get: 2L+1L=18 which is 3L=18 and L=6 we know that the width is half the length so W=1/2(6) so W=3
