the perimeter of a rectangle is 150 cm. the length is 15 cm greater than the width. Find the dimensions.

 

Answer: So the dimensions of the rectangle are 45 cm for each of the lengths and 30 cm for each of the widths

Step-by-step explanation:

w=x

L=x+15

P= 2L +2W

150cm= 2(x+15) + 2(x)

150 = 2x+30 +2x

150-30= 4x

120=4x

30= x

L= x+15

L=30 +15

L=45cm

W=30cm

Checking

150cm=2(45cm) +2(30cm)

150cm= 90cm+60cm

150 cm= 150 cm
