Marisol is painting on a piece of canvas that has an area of 180 square inches. The length of the Painting is 1 1/4 times the width. What are the dimensions of the painting

Sagot :

let x be a width
1 1/4x be the length (or it can be 5/4 i prefer this one)

formula for rectangle
lxw=a
5x/4(x)=180
4[5x^2/4=180]4
5x^2=720
x^2=144
x=12

so width is 12 and length is
5x/4
5(12)/4
60/4
=15

Answer:

The dimensions are 12 by 15
